  1. Identifying noises from air vents
    3 October 2023

    We’re nearing that point of the year where arguments will begin about turning on the heating. However, this is also the time where people start to notice issues. They may have not used the heating in five or six months. So, the first use after such a long period could result in strange noises from the boiler, air vents, and other areas. We want to have a look at some of the causes here. Then, if you need a vent silencer or another solution, we can provide it.

    Popping

    The most common sound from vents will be popping. It happens simply because the ducts are cold metal. So, when hot air goes through them, they expand. The pops happen because of the expansion. They generally stop once the metal has had time to heat up.

    Other noises

    While popping is natural, you may hear other noises from the vents. If you do, they are generally coming from the boiler or AC unit, or because of something in the ducts themselves. It could be as simple as dirt or a loose fan.

    The best thing to do here is inspect your boiler or AC unit. If you can track the noise to it, you can ask an expert to take a look. They may find the appliance needs cleaning or repairs. If there is still noise, you may need a vent silencer.

    Some noises can occur because you are making the boiler or AC unit work harder than it should. There are two major causes of this. First, you may have vents that are closed. It can make the appliance work harder, increasing the stress and causing noise. Secondly, you may have dirty filters or ducts. Again they make the appliance’s job harder, so it can get noisier.

    Finally, it may be an issue with the ducts. They may be too small to meet your heating needs. Or, they could be the wrong shape. Generally round ones are the quietest, whereas square and rectangular ones are louder. Another issue could be the thickness. Thinner materials are more prone to expansion.

    Speak to us to order a vent silencer

    Ventx knows how much of a terrible impact noise can have, especially in commercial and industrial settings. The sounds here can put people at risk, including anyone who works and lives in the area. They can also be detrimental to the environment and wildlife. Plus, the noise can mean significantly higher costs for businesses in terms of repairs, maintenance, and replacements.

    Luckily, we can offer solutions. Thanks to our extensive knowledge of acoustics and engineering, we have the ability to produce bespoke silencers. It could be a vent silencer, models for HVAC units, or even solutions for noise control valves or exhausts. So, contact us to discuss your needs.

  2. Blocking vs. absorbing sound
    3 October 2023

    Staying in a noisy area for too long can cause damage to your hearing. If the noise levels are high enough, even a short amount of exposure can be detrimental. The best thing to do is install the right equipment to keep things as quiet as possible. We can help by providing the finest attenuators on the market.

    When it comes to reducing noise, you must know the difference between absorbing and blocking sound. That is what we want to discuss here.

    Blocking

    Heavy massive materials, in a relative sense, get employed for blocking sound. Examples include concrete block and gypsum board in the construction industry. The sound waves physically can’t enter the material, so it can block it.

    Sound can move through materials

    If people have concerns about noise, they often ask if they can simply add some acoustic panels to their walls. It is critical to realise that porous absorbers can’t block sound. By definition, they have several compact interconnected voids that sound moves through.

    Open-cell foam and fibreglass are examples. The sound wave loses energy via friction between the fibres/void walls and air particles of the material it is moving through. If a sound wave is able to pass into a material, it is also able to pass through. Thus, it is incapable of effectively blocking sound.

    Sound absorbing mechanisms are utilised to lower noise within a space. They are able to lower the echoes, reverberation time, or stop the focusing of sound that is reflected from curved exteriors.

    Batt insulation

    So, why does batt insulation within a gypsum board partition enhance the sound blocking capabilities? The reason why is that you can reduce the sound that passes through the initial layer of gypsum board. It can do this by absorbing a bit of its energy before it is able to reach the second board. The batt insulation is still working as a sound absorber rather than a sound blocker.

    Solutions like these can work in an office setting. For an industrial complex however, you will need to take a different approach. With a sound attenuator, you can meet your noise level requirements. They will absorb the noise and protect people in the area.

    Speak to us about attenuators

    At Ventx, we have aided many clients with their noise reduction efforts. With the right solutions, they can make their facilities more suitable to work in. At the same time, they can meet the UK environmental standards for noise pollution.

    So, if you need our attenuators, please get in touch. We’d be happy to design one for you.

    Blocking vs. absorbing sound
  3. Are sound attenuators and elbows interchangeable?
    3 October 2023

    A lot can go wrong because of excessive noise levels. It can harm people and the environment, cause distractions and injuries, and can even damage equipment. Industrial environments in particular can be terrible for how noisy they are. What you may need is to install the right products to combat the sound. We’re a business that helps clients to do this. We do so by offering attenuator and silencer merchandise in a myriad of forms.

    There is one common belief about a having collection of elbows close to an air handling unit. It is that they can gain the same insertion loss as a manufactured duct sound attenuator. One true detail is that elbows aren’t as expensive as their counterparts. But, we have to wonder what acoustical performance people can actually obtain with this ‘cost efficient’ substitute. That is what we are going to talk about here.

    Comparison

    Let’s compare these two designs. For any variety of elbow, the width has to equal or surpass 30 inches. This is the only way for you to get any insertion loss at 63 Hz. A 30 inch wide elbow only supplies a mere 1 dB of insertion loss at 125 Hz. Usually, these two frequencies are of concern when lowering sounds from AHUs.

    At 63 Hz, an elbow needs to be 60 inches wide at minimum for it to break into the IL domain of sound attenuators at 4 dB. The width dimension here is a minimum of 30 inches for 125 Hz. To gain this quantity of IL at 125 Hz, your elbow needs to be 60 inches wide at least.

    As for sound attenuators, they usually have 4-10 dB of IL at 63 Hz. At 125 Hz, it is 8-20 dB. Certain designs come with considerably higher IL than this.

    For smaller elbows, it can clearly be seen that the IL equivalence between sound attenuators and elbows is troublesome or impossible to obtain. With bigger duct sizes, you’d need to carefully design the system to gain equivalent low frequency IL.

    For greater frequencies, sound attenuators tend to offer 20-40 dB of IL in the mid frequency bands. With the highest tested frequencies, it is 10-15 dB. Let’s say this is where you need IL. A sound attenuator will surpass a series of elbows.

    Other key things to remember

    Furthermore, to stop aerodynamically induced sounds, airflow velocity has to be slow enough. Also, you need to space the elbows far enough apart. You need extra sheet metal in both scenarios. This increases the price of the ‘cost effective’ elbow configuration.

    Moreover, attenuators will accomplish the IL in a far shorter distance. This is an attractive feature for HVAC set ups where there are limits on space. It is the same for ones that enter acoustically sensitive locations quickly.

    Having covered all this, the “costly” sound attenuator may not seem so expensive after all. The elbows may be more costly than you expect. More importantly, the extra investment can mean better results.

    Speak to us if you need an attenuator

    At Ventx, the solutions we supply serve multiple purposes. For one thing, they keep people safe from the negative effects of excessive noise. Second, they allow you to adhere to the established UK environmental standards. This is crucial today and can have a big impact on how people view your business.

    So, if you have an industrial site that needs our solutions, please get in touch.

  4. How do we select the right industrial silencers?
    1 September 2023

    Spending too long in a noisy industrial setting isn’t good for our health. Knowing this, employers need to have the right measures in place so people are safe. We’re talking about installing industrial silencers. There are various models, including in-line, vent, and discharge. Ventx can design them all, creating bespoke ones for each client.

    Industrial mufflers and silencers attenuate and absorb noise from machinery and different sources. They do so for regulatory compliance and to improve performance. The mechanisms use several basic designs.

    Different designs

    Mufflers and absorptive silencers use sound-deadening substances, compounds, and fabric. As a result, they absorb the sound energy coming from air or gas flow.

    Reactive mufflers and silencers use complex passages and/or chambers for noise attenuation optimisation. At the same time, they preserve application requirements such as airflow and pressure drop.

    Hybrid designs make use of reactive and absorptive features. They combine acoustic materials and airflow path management so they can minimise noise.

    Active noise cancellation devices use sound sensors. They do so to characterise the noise-cancelling speakers and sound profile to generate sound 180º out of phase with the airflow sound.

    An analysis

    Choosing industrial silencers, whether in-line or other models, demands an analysis of three things. These are mounting attachments, performance specifications, and physical specifications.

    Mounting attachments include pipe clamps, flanges, female threads, and male threads. You need to select the right one to ensure the silencer will remain in place.

    Physical specs include outlet and inlet size. Some installations possess an oval, circular, or round cross section. Others are rectangular or square. The silencer must be the same shape or it won’t fit.

    Performance specs include maximum flow rating, pressure rating, and noise attenuation. We measure noise in decibels (dB) and then express it as a performance curve over the audible frequency range. For pressure, we measure in pounds per square inch. Finally, we measure flow in standard cubic feet per minute.

    Apps

    To finish, let’s go over some applications for the silencers. One is a pressure relief valve silencer. They lower noise from blow offs. Another is a turbine silencer. They offer attenuation on the outlet and/or inlet port of turbines. As for a vacuum pump silencer, they lower noise at the outlet and/or inlet of pumps. Last on our list is a chimney silencer. They are specifically for combustion exhausts, like industrial furnaces and ovens.

    Speak to us if you want in-line industrial silencer or other models

    At Ventx, we provide silencers from our UK base. Our team has worked with an impressive list of clients. Each one has required a different installation for their unique needs. We’ve been able to help them every time with noise reduction as well as health and safety improvements, and boosting performance.

    So, if you need our aid too, feel free to speak to us. We can deliver the best products, including reliable in-line silencers and more.

    How do we select the right industrial silencers?
  5. The effect of background noise on reading performance
    1 September 2023

    A lot can go wrong because of industrial noise pollution. The solution is to use specialist equipment capable of keeping the sound levels down. We are a company responsible for designing intake silencer installations and other products. Once you start working with us, you can make noises a thing of the past.

    Do you question whether background noise affects someone’s ability to learn and remember? According to some research, sounds can negatively influence the reading comprehension of students. Others have concluded that background sound does nothing. There is even research out there to suggest that music can make it better.

    As you can see, things are a bit muddy. With so many distinct views on noise’s impact on reading, it can be difficult to determine what to believe. Let’s have a closer look at noise and its effect here. Then if you need a solution like an intake silencer, we can help.

    Negative impact

    Research shows that background music, speech, and noise each have a small but negative effect on reading performance. This is due to how the sounds can affect concentration. Such circumstances make it difficult for people to pay attention to what they are reading.

    Children are vulnerable to sounds

    There is other research saying that even though background sound can improve positive emotions and sports performance, reading suffers. Children can be particularly vulnerable to environmental noise’s negative effects. This is possibly due to their cognitive functions being less automatised. So, they are more vulnerable to disruption.

    If children are doing a reading comprehension task and there is noise in the background, they may not do as well as they would in a quieter setting. The reason is that brain resources are also going to listening to the sounds. It can weaken focus and concentration. There is even evidence to suggest that music involving lyrics results in a bigger distraction. Again, the brain could be attempting to decipher them rather than concentrating on the work.

    More harm than good?

    Loads of research exists on the effects of background sounds while reading. The question is whether it does more harm than good. The specifics originating from the most relevant research tells us it does. People exposed to a large quantity of noise can expect decreases in their reading ability. Anyone in a noisy setting who is attempting to study might find focusing hard. Even if there is research showing there is not much impact, you are better off being safe rather than sorry.

    Speak to us if you need an intake silencer or other solutions

    At Ventx, we have worked with many clients throughout the years. Each one has their own specifications that we must meet. For example, it may be an industrial site that also has an office or training facilities. The latter spaces need to be quieter so people can work and study. As a result, it can be necessary to reduce the noise. We can apply our experience and resources to achieve the best results here.

    So, if you need an intake silencer or another model, get in touch. We’ll design it for you, ensuring it can maximise the noise reduction.

  6. Understanding why blowers and compressors need inlet filter silencers
    1 September 2023

    Noise pollution is troublesome for a myriad of reasons. For example, it can harm people and their performance at work. Plus, it can damage sensitive equipment and cause big environmental issues. To prevent it, you need to use the right utensils. This is what we specialise in. Ventx designs and then manufactures inline silencers and many other models to suit varying situations. With them, you can control the noise coming from all kinds of machinery.

    Blowers and compressors exist in various working environments. There are numerous applications for them. Examples include inflating tyres and powering dentistry tools. At times, you may not even realise they are around if they use an air muffler or filter silencer to lower noise. However, if there isn’t one the noise can be a dead give-away of their presence.

    An air compressor muffler is a contraption utilised to lower excessive noise created by a blower or compressor when it is operational. Another name for these devices is silencer. You can find them in various configurations. These include filter silencers, breather vent silencers, and tubular silencers.

    The filter silencer’s purpose

    A filter silencer is sometimes called a compressor or air muffler. The silencer supplies filtered air to safeguard equipment. Apart from this, it also offers efficient noise reduction, lowering the decibel level. Most importantly, it softens the pitch created by the blower or compressor. The intent is to make a loud mechanism quieter so the noise is more bearable for our ears. This dual function separates the filter silencer from other compressor mufflers and air mufflers; they only address noise.

    There is a basic demand for inlet filtration on blowers and compressors; it is keeping moisture or particles from entering equipment. They can cause harm to internal components. In dusty working environments, airborne particles can be pulled into the blower or compressor during operation. The particles can be very abrasive, so they tend to negatively influence the normal performance of equipment.

    Bringing clean air in is essential. This is both for protecting the equipment and the downstream procedure. For these reasons, you are best off utilising a dual-function filter silencer to both protect machinery and limit noise.

    Talk to us if you need any kind of inline silencer

    At Ventx, the industrial silencers we supply benefit a massive range of stakeholders. They keep workers and visitors to sites safe from the adverse effects of noise. Plus, they can reduce the impact on equipment. Also, you often need silencers and the like to adhere to the UK’s environmental standards. These are in place to safeguard the planet.

    So, if you are in need of an inline silencer or other solutions, feel free to contact us. We recommend you think about silencers as early as possible, preferably at the design stage. However, we can provide retrofitting in many cases too.

    Understanding why blowers and compressors need inlet filter silencers
  7. Noise’s effects on plants persists after removing the source
    1 September 2023

    Industrial sites typically create a large amount of sound. It is troublesome because it can cause a host of issues for those that work there. It can also have a big impact on plants and animals in the surrounding area. Some of the problems can be permanent too. For you to avoid all of them, it is necessary to use the proper equipment. We are talking about the likes of gas vent silencers and other models.

    The impact of noise on plants

    Following research performed on plants and trees, those involved concluded that it influences them in several major ways. Scientists from the California Polytechnic State University did the study. It shows that human noise pollution influences the diversity of plant life in an ecosystem. This was the case even after the removal of the noise source. It was the first study to examine the long term influences of sound on plant communities.

    The U.S. National Science Foundation research happened close to natural gas wells in New Mexico. The operations were using loud compressors to help generate natural gas. The researchers found there were 75% less piñon pine seedlings in loud locations when comparing to quiet ones. The tree reduction was likely the consequence of the noise driving away a certain bird. We’re talking about the Woodhouse’s scrub jay. They plant thousands of pine seeds whilst storing them for eating in winter, so the noise scaring them away has a huge impact.

    Removing the noise

    The companies did change the sites of these gas wells and disposed of the compressors. After doing this, the locales became quiet. However, there were still fewer saplings and seedlings in comparison to sites that had never had compressors. The lower count was due to how long the site was noisy for. The piñon pine seeds still weren’t sprouting after they took care of the noise.

    Noise pollution’s effects are influencing the structure of the woodland communities. But, we are witnessing that removing the sound source does not necessarily lead to an immediate recovery of ecological function. This work reveals an important fact about sounds created by huge-scale human activities. They can have long term, unknown ecological consequences. It works to aid us in better understanding how we can manage how we impact the planet.

    Talk to us if you need gas vent silencers and more

    At Ventx, we have a team of experienced, innovative, and flexible technicians. They know how difficult noise can be to accurately predict. As such, we use advanced computer software to model it and then devise all our designs. With this approach, we can produce the ideal products.

    So, if you need gas vent silencers and other models, please don’t hesitate to contact us. We recommend you consider noise as early as possible, especially with plants.

  8. Understanding why your boiler is noisy
    1 August 2023

    Industrial noise pollution causes all kinds of problems, some of them permanent. It can inconvenience you and your workers, as well as anybody living in the area. With the right equipment though, you can lower the noise your operations produce. We can set you up with discharge silencer products and a host of other solutions. The bespoke models can help to make everything quieter.

    Are you having a hard time figuring out why your boiler is being so noisy? Boilers making loud noises can be annoying and very disruptive. In some cases they can be loud enough to be dangerous.

    If it’s just noise, you may be able to install a silencer to reduce the sound. In other cases though, it could be something more worrying. We are going to discuss some of the reasons why your appliance might be noisy. This way, you will know what approach to take when you hear certain sounds.

    Limescale or heat exchanger issues

    The first reason you might have a noisy boiler is due to limescale build up or a faulty heat exchanger. Noises here include clanging, banging, whistling, and kettling.

    The accumulation of scale in pipes, the heat exchanger, and connections commonly happens in hard-water areas. It can cause the sounds we mentioned above. The limescale will attach itself to the pipework and components. Consequently, hotspots where hot water gets to high temperatures will show up. When steam bubbles pop, you will hear the noises.

    Limescale is something you will want to deal with ASAP. It could cause you to replace the heat exchanger or your entire boiler if it gets too bad.

    Central heating sludge

    Another problem is central heating sludge build up. It can cause whistling and kettling.

    This problem happens in every system. As the inside of pipes, radiators, and components degrades, it breaks off into deposits. As it moves through the system it will make clicking, trickling, and tapping sounds. This is the particles hitting the sides of radiators and pipes.

    Alternatively, the sludge will attach itself to components of the boilers. This will cause an issue similar to the scaling.

    Airlocks

    The last reason for noise we will discuss is an airlock in the boiler pump. You will hear banging noises with this one. Airlocks in your central heating do happen. Normally, you will hear the noise a few minutes following you turning on the boiler. It can also happen when you run hot water.

    Talk to us if you need a discharge silencer

    At Ventx, we provide industrial silencers that keep everyone safe. Our experience is extensive, with decades in both acoustics and engineering. As a result, we can design bespoke solutions for most problems. This can include new and existing facilities.

    We are able to provide discharge silencer models and others to meet your particular specifications. So, please let us know if we can help.

    Understanding why your boiler is noisy
  9. The truth about noise barriers and acoustic panels
    1 August 2023

    Noise can be troublesome for a multitude of reasons. This is especially true in the workplace. Some of the damage it can cause could be permanent. To prevent this, you’ll need to lower the sounds produced by your machinery. You can use our silencers to do so. It’s possible to install them on a discharge vent, as well as other outlets including exhausts and more.

    Noise mitigation is often necessary to adhere to permits for all sorts of projects. By misunderstanding the most efficient noise management methods, you can derail your project. This will result in a waste of money and time, so you need to avoid it.

    Something else you should know here is that there are several noise myths. These can point you in the wrong direction. However, if you know what they are, it’ll be possible to lower noise’s effects defensibly and responsibly. Let’s look at two of the main ones here.

    Barriers are a universal solution

    The first myth is that noise barriers can solve any issue. However, by themselves they are only typically able to minimise mid-frequency sound by 10 to 15 dBA within 100 feet of the battier. Some noise prediction models reveal sound reductions exceeding 20 dBA. This is for receptors hundreds of feet away from barriers.

    Results from a model could satisfy project approval requirements. But, once operations start and you have the barriers in place, it may become clear that the noise levels you were estimating don’t match operating conditions. The efficiency of barriers is restricted by the fact that sound waves diffract around and over them. Atmospheric effects on sound travel exacerbate this problem. So, noise barriers often become ineffective past 500 feet.

    Acoustic panels can solve all issues

    Another myth is that acoustic panels can overcome any noise issue. In reality, their purpose is to limit unwanted reflections that cause echoes or reverberation. So, only using them will solve a problem exclusively relating to these two factors.

    We’ve become comfortable with seeing acoustic panels installed on walls or ceilings. Or, they can be a set of porous tiles that completely cover ceilings. What we’re implying here is they have absorptive attributes. Alternatively, we think they can absorb a lot of sound energy.

    The truth is that acoustically absorptive substances only manage sounds that reflect off exteriors. This is at a distance from a listener or source. They don’t influence the sound that travels straight from the source to the listener. Not to mention, there are many noise concerns that only silencers can address.

    Talk to us if you need help with silencing a discharge vent

    At Ventx, we make all our silencers at our UK base. We’ve been able to satisfy a lengthy list of clients. All of them have different, noisy jobs that put people and the environment at risk. With our merchandise however, they can operate safely and efficiently.

    So, if you need a silencer for your discharge vent, make sure you come to us. We’d love to help, and can devise the perfect noise solution for any needs.

  10. An introduction to industrial boiler blow downs
    1 August 2023

    People use different methods to try and combat the noise in their work areas. Some are more effective than others are. Using a blow down silencer, as well as other designs, is one of the best options. We are an establishment that designs, makes, and installs these critical utensils. With them in place, you will have a more comfortable and safer workspace.

    Boilers are crucial to the operation of countless industrial and large commercial facilities. You need them for heating and other applications such as controlling water chemistry and supplying steam. However, there are potential issues just like with smaller domestic appliances. Most of them come because of undesired impurities in the boiler water. They can cause unnecessary operating conditions. This includes the deterioration of instruments and values, as well as noises like popping.

    What you likely need here is boiler blow down. It can preserve the correct water chemistry by getting rid of impurities and deposits. This will aid you in running an efficient and safe operation. What we are going to do is explain what a boiler blow down is, some methods of doing it, and types.

    What is it?

    Boiler blow down is a procedure where you remove water from the system. This helps to eradicate sludge, suspended soils, and impurities. It is important for managing water parameters. It also helps to prevent the risk of blockages.

    The level of blow down you need relates directly to the quality of water that is going into the boiler. Keep in mind that the better your water purity, the less blow down you need. This is because the level of minerals will be lower as quality increases.

    An important thing to keep in mind here is the process can create a lot of noise. So, you may need a blow down silencer to reduce the volume.

    Blow down methods

    There are two separate approaches you can use to do a boiler blow down. These are automatic and manual. The majority of operators know about the latter strategy. It demands the operation of controls and valves to get water out of the system or boiler. You need to do this every time.

    However, there are systems you can put into place to automatically do these tasks at the right intervals. Automation can be very useful because it means you don’t need the human input.

    Types

    To finish, we will talk about the available types of boiler blow down. There are three main options.

    The first is surface or continuous where you remove from the top of the water level.

    Secondly is bottom blow down, also known as intermittent. This is the most common option, and removes from the base of the boiler to get rid of impurities.

    Finally is water column. This is often the forgotten method, but it is still crucial. It involves the blow down of the water column, gauge glass, and any pipes or valves here. These are used for measuring the water level, so it is important they are free of impurities.

    Talk to us if you need a blow down silencer

    At Ventx, we provide silencers that have many benefits for workers and visitors of industrial sites. Not only this, but you need them to adhere to the UK’s environmental legislation. You could have a plant that is in the design stage or an existing site that is now struggling with louder noises. Whatever the case, we can help.

    So, contact us today if you need a blow down silencer or any other style. We can deliver something bespoke for you, reflecting the unique operating conditions.

  11. Navigating work meetings with hearing loss
    1 August 2023

    Industrial noise pollution isn’t something you want to put up with. Depending on the sound level, even short term exposure can lead to problems like hearing loss. Ours is a business that helps with this issue. To do so, we supply blow off silencer equipment and several other models. They will keep the decibels lower and productivity higher.

    One of the troubles with hearing loss is that it can make partaking in work meetings difficult. People may struggle to follow presentations or conversations in big rooms or smaller, noisier ones. By planning in advance, you can minimise some of the communication barriers. As a result, you will be able to participate more efficiently. Let’s go over some tips you can use to manage meetings when you have hearing problems.

    Arriving early

    Firstly, getting there early enables you to get yourself situated. If there is going to be a speaker present who you’ve not met before, make the introductions. Let them know you suffer from hearing loss too, if you are comfortable doing so. Tell them how they can best help you. This way, the speaker will be aware of your needs and can make the necessary adjustments. For those that use hearing aids with directed microphones, you will have time to set them up.

    Pick the right seat

    You also need to select your seat thoughtfully. You need to sit where you can see the speakers clearly. Here, you will have an easier time reading their facial expressions and lips if you need to. If it’s a round table meeting with individuals you know, sit across from or next to those who you think it will be hard to hear from. For auditoriums, think about sitting closer to the front of the room. In addition, keep away from sources of background noise.

    Notes

    Lastly, some speakers could provide written notes if you ask ahead of time. You will be able to use them to get a sense of the topic they are discussing. It will reinforce the details you hear during the presentation. Some larger companies could have note-takers. They will jot down everything. After the meeting is over, you can request a copy of the notes.

    Making spaces quieter with blow off silencer equipment and more

    Hearing loss is a serious issue that can cause many inconveniences and serious problems. Employers have an obligation to think of the health and safety aspect of loud noise. They should work to mitigate the sound when it is dangerously loud for short or long term exposure. The best way to do that is to use silencers. They can fit to noisy machinery, HVAC systems, and more. It will make workspaces quieter and safer.

    At Ventx, we have been designing high quality silencers for over a decade. We use our 35 years of quality manufacturing experience as well as 40 years of acoustic knowledge to get the jobs done. Our people are able to create blow off silencer models that tick all the right boxes. There are many more silencers we can provide too, including options for vents and more.

    So, if you need help with noise, talk to us today. Our solutions can reduce the risk of people suffering hearing loss and other problems.

  12. Energy plant noise levels

    Heavy noise levels are often unavoidable, which isn’t good. If people are exposed long enough, they can suffer from several health issues. The worst of them can be permanent, such as hearing loss. To avoid any problems, businesses should ensure they have the right solution in place to reduce the sound and protect people. We aid clients with this by supplying natural gas silencers and other designs.

    In places like energy plants, hearing what others say is the most important thing in communication. These facilities are noisy locales. The noise level can vary by the plant’s power source. Your location relative to the operating equipment is also important. The closer you are, the louder it will be, and therefore the higher the risk.

    An 80dB sound level is considered unpleasant, with 85dB being the threshold for loud. Then there is 110dB, which is extremely loud. The limits for possible permanent hearing loss and pain are 150dB and 140dB respectively.

    Gas and coal

    As for the mean noise levels, they are sort of similar for gas and coal plants. Both average between 80 and 85dB. But, long term exposure to noise in a gas facility is normally greater. Here, there is a time-weighted average of 78dB vs 69 for coal.

    Wind power

    Relatively speaking, wind plants are quiet. This is in spite of the complaints made by those who oppose the construction of turbines close to their homes. The noise is around 55dB immediately adjacent to the actual turbine. As for 300 metres away, the sound averages a mere 43dB. This is the minimum distance to nearby homes. At 500 metres, noise levels can fall to just 38dB.

    Noisy equipment

    However, noise from separate pieces of equipment in energy plants can reach as high as 155dB. This is when they have diesel engines or combustion turbines. Such a figure can lead to health and safety problems. Even at lower levels, noise exposure can have a cumulative effect. This can cause other health complications like cardiovascular ones. Workers may make compensation claims as a result.

    Choose a natural gas silencer or another model

    With the risks in mind, you are far better off having a noise reducing solution like a silencer in place in the plants. The silencers can help to lower the volume. They are far more reliable than relying on people to wear hearing protection. Plus, they can lower the general noise level to make it easier for people to communicate.

    At Ventx, we have many years of experience working in industrial silencer design. It’s the same for quality manufacturing and acoustics. Thanks to this deep understanding, we can create natural gas silencers and more for every client.

    So, if you need an industrial noise solution, please let us know.

  13. Effectively ventilating a warehouse
    3 July 2023

    In many cases, warehouses are very basic structures. They are generally steel frames with a simple building envelope. The latter can easily just be metal cladding or panels. However, the simplicity can result in issues with things like lighting and ventilation. We want to look at the latter today, including the importance of HVAC, vents, and why you may also need an air vent silencer.

    The issue

    Warehouses often don’t have a proper HVAC system. It can result in some major issues. They can have a big impact on employee health and safety as well as the reputation of the business.

    The main problem is the air quality can be very poor here. That is especially likely at busy periods when you have lots of people working in the building. If you use equipment like forklifts, the exhaust fumes will also be added to the mix.

    Another issue is the temperature within the building can get very uncomfortable if you don’t have a HVAC system. This can have a massive impact on employees. It could also potentially damage the goods you are storing.

    What to do?

    The solution here is to ensure you have a suitable ventilation system in the warehouse. As a minimum there should be some vents to allow hot, dirty air to leave the property. You may need fans to direct airflows to these exits. Make sure you get the placement of each air vent correct. This includes having them close to any equipment to release fumes.

    In some cases you may need a formal air conditioning system. You can place units in strategic locations throughout the building. These can pull out hot air and deliver cool in return. It may even be a good idea to choose destratification fans to mix and circulate air.

    Another thing to look at is the humidity. It can have a huge impact on temperatures in the building and again may be responsible for damaging products. You need to control how humid the warehouse is to make it more comfortable. A dehumidifier may be necessary to help with this. However, some HVAC systems have humidity controls.

    Finally, you may need to look at insulating the building. As we said above, many warehouses are simple, basic structures. They can often lack insulation. That means if it is hot outside, it can heat the interior. Similarly, when it is cold it can make it freezing inside. The solution is to insulate every part of the structure, including the exterior walls, ceiling, and floor.

    Silencers

    An important thing to note here is you may need to consider noise when you make changes. You might need a silencer for each air vent because they can get noisy. It could also be necessary to get them for fans and other equipment to address the operating sound.

    The last thing you want is to improve the ventilation only to make the workplace unpleasant because of the sounds. In some cases this could be just as harmful to employees. So, it is a good idea to think about silencers. It is also easier to do this from the outset before you commit to a HVAC system, fans, vent placement, and other things.

    Talk to us for an air vent silencer

    Ventx is one of the UK’s leading industrial silencing specialists. We know the hazards noise can cause in a variety of settings, whether it is massive plants or smaller storage facilities. Wherever there is a risk to people or the environment, it is a good idea to bring the volume down.

    We are happy to provide bespoke solutions for all clients. They can be air vent silencers, solutions for HVAC, fans, and more. We even cater for things like steam boilers and heavy plant. So, if you need help, contact us.

  14. When loud is too loud
    3 July 2023

    Noise pollution from industrial environments can create a host of problems. As a result, businesses need a preventative solution in place to keep everyone safe. We can help here by supplying silencers for steam vent installations and much more. In fact, we can cater for other forms of machinery as well as HVAC systems. If there is something in your property or on the site that is creating too much sound, we can offer a helping hand.

    It can be difficult to tell how loud noises are. If you don’t understand how loud is too loud, there could be trouble. To help, we’ve put together a small guide.

    Measurement

    To start with, we measure noise using the decibel (dB) scale. This reflects the sensitivity of our ears to separate frequencies and levels of sound.

    To give some examples;

    • 0dB is the quietest sound healthy human ears are able to hear.
    • For 60dB, this is an ordinary spoken conversation.
    • An industrial fire alarm is 97dB.
    • Then there’s 130dB, which is an aeroplane that is taking off 100m away.
    • Lastly, 140dB is the level where noise causes pain for most of us. However, some individuals can find lower levels painful as well.

    Long or repeated exposure to noises at 85dB or over can result in hearing loss. If there is anyone working in a loud environment with sound levels reaching 80dB, employers should do a risk assessment. Any information they find should also get passed onto the workers.

    Safe exposure

    The safe exposure time for 85dB is as much as eight hours a day. You will likely be exposed to a fair amount of sounds exceeding this during the period. The exposure time adds up too. Sound intensity doubles with each 3dB increase. So, the safe exposure time halves. As a result, four hours is the safest exposure time for 88dB.

    You are in danger of hearing damage a mere 15 minutes after spending time in a standard nightclub. Many play music at 100dB. You should use hearing protection here. With sounds ranging from 110-120dB, even a short amount of exposure is dangerous.

    Silencers to reduce steam vent noise and more

    At Ventx, we have more than a decade of experience in silencer design. Due to this, we have no trouble providing a solution for almost any given situation. It could be vents on a noisy boiler or pipe, a loud generator, or something more specialist like an autoclave.

    So, if you ever need a steam vent silencer or any other model, please give us a call. We create bespoke ones for each client to make sure they work properly and don’t cause issues.

    When loud is too loud
  15. Is it time for a generator silencer?
    3 July 2023

    Industrial silencers are essential installations. Their job is to keep the noise in these tough environments to a minimum. Constant exposure to loud noises can create a host of issues, some of which are permanent. If the noise is loud enough, even shorter periods of exposure can spell trouble for people, sensitive equipment, and the environment. Our silencer solutions aim to prevent all of these problems.

    Were you aware that numerous cities have silent zones to lower noise emission levels? These include areas like schools, hospitals, and other places that could have a higher sensitivity to loud sounds. You need to think about the noise levels at all times, including when using plant such as generators.

    If you’re aiming to minimise the noise coming from your generator, consider using a silencer. These silencers are a mandatory piece of equipment for various industries. They aid in restricting the noise from the plant. As a result, generators become less annoying and obtrusive. You may be in the market for a new silencer. If so, there are some things you should know about industrial silencers.

    Where to use them?

    Generator silencers tend to get utilised in commercial settings. Examples are restaurants, hotels, and office structures. They can be useful for providing power if there is no mains connection or it can’t supply enough electricity. Some are also a backup in case the main supply cuts off.

    The benefits

    There are benefits to employing generator silencers in places like these. Most obviously, you can limit noise levels in the area. Employees and customers can enjoy a more pleasant environment. You also protect any other equipment that may have sensitivity to the sound.

    Also, a generator silencer can aid you in lowering the level of pollution the plant creates. This can augment air quality and safeguard the health of any exposed to the fumes.

    Lastly, a silencer can increase a generator’s lifespan. It does so by minimising wear and tear. You will save money on repairs and replacements in the long run.

    Using silencers

    Now, we’ll discuss when it is time to use one of these silencers. A generator can be a fantastic asset for businesses. They provide a dependable source of backup power in outages. However, they are loud. When not muffled correctly, they can create noise pollution. Due to this, you should consider installing a silencer where the generator will cause a lot of sound.

    There are some factors to consider when deciding whether you need a silencer. The type and size of the generator is important, as is the business location. Think about the sensitivity of locals to noise pollution as well.

    Do you need industrial silencers?

    If you determine that a silencer is necessary, you have a plethora of options available. It is vital to choose one designed specifically for the model and make of the generator in use. By taking these steps, your plant won’t turn into a nuisance for everyone else.

    At Ventx, the industrial silencers we provide benefit workers and visitors to your sites. Besides this, you need them to meet the UK’s environmental standards. You could have a site that needs our bespoke models or a plant at the design stage. Whatever the case, we can help.

    So, call us today to get your hands on our exceptional silencers.

  16. How many fan silencer designs exist?
    1 June 2023

    There is a lot that can go wrong due to industrial noise pollution. It’s our job to keep these issues from happening. We do so by supplying top tier industrial silencer designs. Our silencers can minimise the noise coming from a myriad of sources. This includes fans, duct work, generators, compressors, and multiple forms of machinery.

    Industrial fans are rotating devices. They circulate air and supply ventilation for plants and other properties. Whether large or small, the design of such fans enables them to generate noise. This is normally above the recommended decibel level in a manufacturing environment. Luckily, there are silencers to help mitigate it. They offer noise attenuation when put at the outlet or inlet of a fan.

    Similar to other industrial contraptions, the fan’s performance depends on certain factors. This includes whether they are suitably sized for a certain application. In this post, we want to talk about some of the basics of these fan silencers. Specifically, we’re going to discuss the different kinds that exist.

    Rectangular silencers

    These are designed to suit rectangle ductwork in a cost efficient way. Such silencers provide high sound attenuation as well as low-pressure losses. Furthermore, you can stack them into huge banks. This removes the costly transmissions you can find in other silencer variants.

    Elbow silencers

    This type is preferable for applications with little space. Also, you can use them when there is very high insertion loss and moderate pressure drops. The models come with elbow baffle passages, which limit pressure loss. Furthermore, you configure them to match most duct sizes without using transitions.

    Axial fan silencers

    You can apply these to axial fans. Also, they are engineered to supply sound attenuation at the source. They enhance aerodynamic performance at the outlet and inlet of the fan.

    Circular silencers

    These models are meant for maximum attenuation with low pressure drop. They are preferable when you use round ductwork. In addition, they eradicate the demand for square-to-round. These are ones that produce unwanted pressure loss.

    Speak to us to get the right industrial silencer

    At Ventx, we’ve had the chance to work with an extensive list of clients to meet their noise reduction needs. Thanks to our wide range of silencer designs, we help people working in a myriad of environments. Our silencers keep staff and visitors safe. Also, users can meet the UK environmental standards.

    So, if you need our help to create an industrial silencer, please get in touch. We have the experience to deliver the best style for any situation. This could be a brand new facility or one that has been operational for a long time.

  17. What do safety valves protect against?
    1 June 2023

    Safety is absolutely crucial in any kind of property. It could be a private home, a school, a hospital, or a heavy industrial facility. Whatever the case, there must be systems in place to ensure everything is safe for inhabitants. There will likely need to be a selection of valves and silencers to address pressure and noise. We can help with the latter, offering safety valve silencer solutions and more.

    An unsung hero

    Most people won’t even know how reliant they are on safety valves. They can be present in every single property in one form or another. This is because they are generally necessary on building systems such as water and gas lines, HVAC, and more. Their role here is to open automatically once pressure conditions become hazardous.

    These valves protect against a number of unwanted situations. We want to have a look at some of the main ones here.

    The most common application for safety valves is to protect against over-pressurisation. It can happen with water, gas, steam, and a wide range of other gases and fluids. If there is no failsafe in place, the pressure can simply build and build until there is a failure. This can result in leaks, rupturing, or even a large explosion.

    The valves can also protection against pressure accumulation. It can happen for a number of reasons, including blockages, the failure of components, or even excess heat. The latter can cause fluids to expand, increasing the pressure.

    Most systems will be designed with specific operating conditions in mind. However, it is surprisingly common for them to change over time. It can happen due to changes in operations, demand, or new additions. It is important to be careful here because a change can have an impact on performance and safety. The valves will be necessary in case the changes exceed safe limits.

    Silencers

    As you can see, the valves protect against potentially devastating failures. They can preserve boilers, pressure vessels, pipelines, and more. However, when you use them, you also need to think about the impact on noise. It may require the use of safety valve silencers too.

    The most effective way to depressurise a system is to release whatever is inside it as quickly as possible. This could be steam, gas, water, or other substances. Doing so can cause hazards in its own right though. The major one is it can generate a huge amount of noise, especially when dealing with gases. Depending on the pressure, it could be so loud that anyone nearby is at risk of hearing damage.

    It is important to manage the risk here. You must think about how close people will be and the level of noise. A silencer may be necessary to reduce the volume.

    Ask us if you need a safety valve silencer

    Ventx is the UK’s top specialist, excelling at delivering silencers that provide the best of all worlds. Each one is bespoke to ensure a great fit. Plus, they are made of high quality materials to provide long term protection. At the same time, they will reduce noise as much as possible. Finally, they have the potential to boost the performance of entire systems.

    So, if you want a safety valve silencer or another model, please contact us. We’ll get you the products you need.

  18. The specifications of pneumatic silencers
    1 June 2023

    We fight against the problems industrial noise pollution causes. Our approach involves designing and supplying a range of silencers. They minimise the noise in various facilities. You can use the likes of our autoclave silencer models to keep noise levels stable. We also excel at pneumatic silencers. All of these devices are high in quality and have reasonable prices.

    Silencing pneumatic equipment

    There are a lot of silencers out there, with the pneumatic silencer being one of them. Another name for them is a pneumatic muffler. They work as outlets to vent pressurised air into the environment. A silencer usually fits onto a cylinder. Alternatively, they go onto 5 or 2-way solenoid valves or other fittings.

    The air that leaves the device emirates contaminants while the silencer works. However, this could create a noise that might harm the surroundings. So, it is advisable to employ a silencer exhaust cleaner. It will restrict damaging materials from getting into the environment.

    Pneumatic silencers are highly cost efficient. Also, they are far simpler tools to lower the noise and contaminants. Another fact is that they come with variable flow rate control. You can use this to manage the speed of a driving device.

    The main function of pneumatic silencers is to outlet pressurised air at a safe noise level. Also, they stop contaminants from exiting your silencer if they are combined with a filter. Silencers will be straight at a valve’s exhaust port. They diffuse air via a larger surface area that lowers turbulence and noise levels. It is possible to install silencers on hoses as well.

    If you need this kind of product or an autoclave silencer, you need to ensure the specifications are right. We want to look at the main ones here.

    Temperature

    Pneumatic models are suitable for low or high temperature applications. Whilst choosing silencer materials, you need to ensure they can work well. They must do so across the operating temperature.

    Pressure

    A device needs to be chosen according to the proper operating pressure. This is in guaranteeing optimal noise reduction. Also, it should lower chances of premature failure.

    Connection type

    Pneumatic silencers are normally linked to ports utilising a threaded male end. This could be on fittings, a solenoid valve, or a cylinder. The right connection enables you to move it from one device or hose to another, and likewise.

    Surface area

    This important specification usually influences the noise reduction, mechanical strength, and the overall size. As a result, it is very important to get it right.

    Do you need an autoclave silencer or a pneumatic one?

    At Ventx, we supply silencers that benefit both workers and visitors of industrial sites. At the same time, you need them to adhere to the UK environmental standards. You can work with us if you have an existing site or a plant that is at the design stage. We will find the best solution whatever the situation.

    So, talk to us if you need an autoclave silencer or something else. We’ll be happy to design one or a suite of them for you.

  19. Hammer noise – A major issue with steam boilers
    1 June 2023

    Noise pollution coming from industrial facilities can cause a host of issues. This is the case for those working inside them and the surrounding environment. We provide tools like our steam boiler silencer to keep noise levels to a minimum. They keep everyone happy and healthy, no matter what side of the fence they are on.

    Steam boilers are known to make a multitude of noises at times. However, it does not mean they should be making these sounds. A properly maintained and installed boiler system should in fact be a quiet one. The sound could indicate there is a problem.

    Water hammer noise is an issue that appears every so often with the boilers. Right now, you are likely wondering why it happens. That is what we are going to talk about here.

    Fail steam traps

    These traps are crucial in two-pipe steam boiler systems. Their purpose is to divide the water from the steam. They do so by trapping the latter in the radiators and enabling the fluid to flow into the returns. When the traps fail, steam is able to freely move through the return pipes that are full of water. This permits water and steam to mingle in the same pipe. The result is water hammer noise.

    Pipe insulation trouble

    Another cause of the noise is insulation problems. If you don’t insulate the pipes it can end up with the steam cooling back to water prior to it reaching the radiators. It makes water and steam prevalent within the mains, so it can generate a water hammer sound.

    Dirty boiler water

    It is important to ensure that water inside a steam boiler is free of debris, grease, or oil. Filthy water leads to uneven steam distribution. Moreover, the fluid can get carried up the steam mains. What this does is produce “wet” steam within them. It can cause water level fluctuation and hammer noise.

    An incorrect water line

    Every boiler manufacturer will recommend a water line you should stick to. This is to guarantee that dry steam can go to the mains. Too much water results in the boiler flooding. It prevents the steam from “drying” and will result in noise.

    A steam boiler silencer can make things quieter

    At Ventx, we understand that industrial silencers benefit both workers and site visitors. At the same time, we know that they are needed to follow the UK environmental standards. The right solutions can lower the noise to provide benefits to all stakeholders.

    What we do to help here is design our silencers to ensure they are the highest quality. We then install them with care if you need us to. So, if you want a steam boiler silencer or a different model, please talk to us. We’ll work with you to ensure the best results for your facility.

    Hammer noise – A major issue with steam boilers
  20. Benefits of removable insulation blankets
    2 May 2023

    Controlling noise levels is much easier with the right equipment and materials. Firstly, you have to get your hands on suitable products. To do that, you need to work with a team specialising in silencing. Ventx is one of the leaders when it comes to industrial silencer design. We have been in this field for years, providing various clients with the correct designs. We can also offer advice about other acoustic solutions.

    Noisy, hot exhausts

    Exhaust systems have the potential to generate a huge amount of noise. They carry sound pollution from engines and other loud machines. Consequently, we install industrial silencers to lower the ambient noise. They stop it from spreading to the surrounding environment.

    However, silencers can produce heat as part of their operation and may need a solution. Insulation blankets for them help lower the surface temperature. This creates an overall lower level of heat in the surrounding environment. Such silencer blankets result in a safer work setting for employees. It can be wise for areas around exhausts, engines, and other high heat, high decibel gear.

    What we want to do here is talk about some of the general advantages to using them. That way, you can see why you should get some if you choose bespoke industrial silencer design.

    More workplace safety

    For one thing, they improve workplace safety. Eradicating every hazard from your workspace is impossible. But, you can take steps to lower the danger of common injuries by using these covers. They create a barrier between the hot equipment and the employees. This helps to ensure people won’t get burned if there is accidental contact. The blankets lower ambient temperatures too by managing heat. It can make the whole area safer.

    Simplifying maintenance

    Secondly, they are able to facilitate routine maintenance. Removable insulation blankets make it easier to pinpoint possible equipment issues before they get worse. Leaving them alone may cost you a lot of money later. You can perform effective and periodic examinations easily here. Then you can do the maintenance to fix each issue.

    Simple to install

    Finally, installation is very easy. The blankets wrap around the key component, whether it is an exhaust or a piece of equipment. They normally use lacing wire fastenings for superior versatility. Other options include springs, velcro, snaps, and straps. So, you can choose the best option for any need.

    Ask us about industrial silencer design solutions

    At Ventx, we have more than a decade of experience with silencers. Our team builds on 35 years of quality manufacturing knowledge and 40 years of acoustic expertise. Putting together everything we know, we are able to create solutions for a wide range of industries. This includes manufacturing, service and petro-chem.

    So, if you need our industrial silencer design service, please let us know. We can work with you from the outset of a project, handling initial designs. Or, you can speak to us if you need to retrofit.

  21. Noise control mistakes you can’t make
    2 May 2023

    Effective industrial noise reduction is essential for any facility. When people work here unprotected, they can suffer multiple negative effects. Some of these are permanent, including hearing loss. The sound can also damage equipment and harm the environment. With the help of our silencers, the noise and issues it causes will be addressed. We design and manufacture many models to suit different circumstances.

    The acoustic experience in a facility can make or break it. You can say the same for many other complexes. There are a lot of noise control mistakes you can make during the construction process. To help you avoid them, we are going to detail what some of them are here.

    Assuming there isn’t an issue

    Firstly, never think that you don’t have a noise problem. Inside a factory, you do have an issue if someone gets exposed to certain sound levels. These are ones exceeding an A-weighing level of 85 dB. Even levels lower than this can be a concern. A 55dB level in a smaller space is a good example.

    Occupants should not have to depend on earplugs or noise cancelling headphones to work efficiently. Within a facility, you should only consider ear protectors a temporary answer. Generally speaking, if communication is troublesome, you have an issue. A more permanent solution would be using a silencer for industrial noise reduction.

    Consider noise control before starting projects

    Not considering noise control at the outset of a project is another mistake. It is possible to treat a noise source post-installation. However, it is typically more expensive and less effective if you compare to designing with measures in mind from the start. Take some time to comprehend your acoustical expectations. Only afterwards should you install the source of noise.

    Failing to use a systems approach

    A common waste of noise control money is not considering all potential sources and paths. Treating one sound source or path but not the others can leave noise at unacceptable levels when you complete a project. As a result, your investment may not provide the solution you need.

    To gain an understanding of the acoustic situation, examine airborne and structure-borne paths. The first noise is often contained to the location immediately surrounding the source. As for the latter, the sounds resonate to other parts of the structure. It is not viable to chase noise throughout the building. You need to stop it at the source by attending to all potential pathways for escape.

    Get the right support with industrial noise reduction

    At Ventx, we have worked with an impressive list of clients, satisfying many specifications and noise situations. We design multiple silencers that work in all sorts of facilities. With them in place, noise becomes a far less worrying issue.

    So, if you would like to know more about how we approach industrial noise reduction, feel free to contact us. We have the skills and experience to provide solutions that work, whether it is a new facility or installing measures in an existing one.

    Noise control mistakes you can’t make
  22. Examining silencer geometries
    2 May 2023

    It is essential to keep noise levels in your industrial facilities under control. Failing to do so will lead to many issues later on, some of which are permanent. To prevent such situations, you may need to attach silencers to your machinery. Our speciality is designing these products. We offer steam vent silencer designs and various others, catering for many different noise sources.

    A vital consideration

    The pressure drop vs insertion loss equation has plagued silencer manufacturers for years. As time has passed, experts have developed standard silencer geometries. Their purpose was to deal with this equation. With backing thanks to a great deal of development and testing, you can apply these designs on an application specific basis. So, you can pick the most suitable unit for your needs. You will be able to obtain the necessary acoustic performance at a rational pressure drop.

    Such designs get labelled based on a particular velocity profile. However, you are able to introduce them to a broader array of velocities. All you have to do is ensure you take an acceptable pressure drop into account.

    Now that we have had a look at all of this, let’s explore the standard silencer geometries.

    Low velocity

    Firstly, we have a design that can provide a big pressure drop. Such geometry supplies an extremely high level of acoustic performance. But, when velocities go past 1000 FPM, pressure drop levels can become unsuitable for most situations.

    Medium velocity

    This is the best all-round performer the silencer market has. The straight through parallel entrance supplies a high degree of insertion loss. At the same time, the tapered tail discharge functions to keep pressure drops to a minimum.

    With such a model, it is possible to work through a series of applications from 0-2000 FPM. You can get a reasonable degree of pressure drop for most of them.

    High velocity

    Here is a design that lets you reach into the 2000-2500 FPM range with a normal product offering. It can do that while you supply outstanding sound attenuation and lower pressure drops in comparison to the other two designs.

    Another use of this design is in lower velocity projects that need very low pressure drops. At times, they can go as low as 200 FPM.

    Get the ideal steam vent silencer

    At Ventx, our industrial silencers will help you keep your workers and visitors safe. At the same time, you will need them to adhere to the UK environmental standards. You might have a plant that is at the design stage or an existing site. Whatever the case, our bespoke silencers can help.

    So, whether you need a steam vent silencer or another model, contact us. We give you the benefit of our extensive knowledge, ensuring you get the maximum sound reduction.

  23. Can traffic noise and air pollution cause high blood pressure?
    2 May 2023

    Traffic noise can be one of the most annoying and disruptive sounds. Nobody wants to be trying to drift off to sleep only to hear loud sirens or cars screeching by on the streets nearby. However, new research shows that the noises can actually have a more serious physical impact on people. We want to have a closer look at the findings and what they mean in terms of noise control.

    The study

    Researchers used UK Biobank data from almost 250,000 people to examine the impact of noise pollution on blood pressure. At the beginning of the study, all the participants aged between 40 to 69 had good health with no signs of hypertension. The study tracked them for a median of 8.1 years with differing levels of exposure to noise traffic based on their address. In this time, over 21,000 developed it.

    The major finding was that people with addresses living near road traffic noise were the most likely to develop hypertension. There was a dose-dependent relationship. So, the higher the amount of noise, the bigger the risk of health problems.

    It was also found that people had the highest risk if they had exposure to traffic noise and air pollution. Pollutants like nitrogen dioxide and fine particles from exhaust gases can have a big impact on heart health.

    Why does it happen?

    While the study shows there is a link, there is no clear reason why noise causes it. However, the theory is that the sound increases stress on the body. In turn that can lead physiological changes such as adrenaline triggers, nerves firing, and inflammation. It can result in an elevation in blood pressure.

    What is the impact?

    High blood pressure can cause a number of health problems. For example, it increases the risk of heart disease, heart attacks, and strokes. It can also cause kidney disease and even damage the eyes.

    Noise control is very important

    The potential health impacts of exposure to traffic noise mean it is important to look at ways to mitigate it. There are lots of options at home and at work. For example, you can look to reduce or block it. Insulating materials can work wonders. Hearing protection can be very useful too.

    Some industries have a very high risk of exposing employees to traffic noise because they involve massive vehicles and people in close proximity to them. It could be logistics, warehousing, or mechanics. Businesses here should take extra steps to protect employees.

    Can traffic noise and air pollution cause high blood pressure?
  24. Industrial pollution exists in various forms
    3 April 2023

    Silencers are needed to keep noise levels down in industrial facilities and the wider areas. There isn’t a universal solution here though. You need to use different designs for individual situations. That is where we come in. We can design suitable diffuser silencer models and any others you need. As a result, we can reduce the noise.

    Pollution is where you make air, water, land, or other parts of the environment dirty and unsafe for use. It happens due to the introduction of contaminants into natural settings. However, the contaminant does not have to be tangible. Things as simple as temperature, sound, and light are also pollutants if you introduce them to an environment artificially.

    Toxic pollutants influence over 200 million individuals across the planet. They can cause a huge number of different problems, including birth defects. Life expectancy can be as low as 45 years in the worst areas due to diseases like cancer. What we are going to do here is briefly discuss the different kinds of pollution that exist. We hope it will help businesses to think carefully about their operations and the impact they have.

    Land pollution

    It is possible for land to become polluted by industrial and household waste. This is one of the biggest environmental impacts of human activity, especially when so much of the rubbish goes to landfill. According to Forest Research, as much as 20,000 hectares of land in the UK is contaminated and not safe to use.

    Water pollution

    This happens when chemicals or deadly foreign materials find their way into water. Examples include fertilisers and pesticides, sewage, and toxic chemicals. The UK ranks consistently as one of worst countries in Europe in terms of water quality. In fact, The Rivers Trust said in 2020 that no river in England or Wales could be classified as being in good health.

    Noise pollution

    This is the one we know all too well in our role to provide diffuser silencer products and other solutions. It is not possible to smell or see noises, but they still affect our environment. It occurs when the sounds reach harmful levels. According to research, direct links exist between health and noise. For example, the sound can cause speech interference, high blood pressure, and illnesses relating to stress. It can harm wildlife in numerous ways too.

    Air pollution

    The air we all breathe comes with a precise chemical composition. Around 99% of it is inert gases, water vapour, oxygen, and nitrogen. Air pollution happens when things that are not typically there get introduced into the atmosphere. A common issue here is when human activity releases particles into the air via fossil fuel burning. The pollution looks something like soot. It contains countless tiny particles that float in the air.

    Light pollution

    Most of us can’t imagine living without electric lighting. However, in the natural world the lights have changed how nights and days work. Consequences of the pollution include serious impacts to various ecosystems and nocturnal activities. Furthermore, artificial light can disrupt plant development.

  25. Take noise seriously and control its risks
    3 April 2023

    Our job is to supply bespoke silencers for industrial facilities and other properties. This technology works by minimising the noise from machinery and systems like boilers and HVAC. They prove useful at reducing the problems noises cause in work environments. We can design and manufacture in-line silencer designs, as well as many others, so rely on us if sound is causing issues.

    Workplace noise poses substantial dangers to our hearing. Without the right equipment and tools, you may be leaving staff members vulnerable to hearing loss. There are several common mistakes people make with workplace noise. To help you avoid them, we are going to go over two main issues here.

    Not taking noise seriously

    Every employer is bound by Health & Safety regulations and legislation. Their industry does not matter. The UK Control of Noise at Work Regulations 2005 establishes what employers must do to defend their workforce. This is from the hazards that excessive noise exposure presents. They are also legally enforceable. As a result, every business should take noise seriously.

    85dB(A) is the level where the law demands that people use hearing protection. At first, this figure seems like a lot. However, it is the same noise a petrol lawnmower makes. Knowing that, it quickly becomes apparent the risk of noise is very prevalent. At 85 decibels, all it takes is eight hours of exposure until people suffer permanent damage to their hearing.

    According to the regulations, measures have to be in place that reduce and control the level of noise we experience in a working day. You are probably wondering how you can do that. Fortunately, we have plenty of silencers available.

    Not controlling risks in the first place

    Another big mistake is not attempting to control noise risks in the first place. Some employers think they can just provide PPE and not look at the actual sound level. Even if you supply your workers with hearing protection, there is still danger.

    In most cases simply supplying PPE isn’t sufficient to guarantee your team is safe. Various employers offer insufficient hearing defenders. They either over-protect their workers or under-defend them. There is also a risk that people won’t use the PPE properly, especially if you don’t give them the right training.

    It might appear as if it is hard to have too much protection with regards to hearing loss. Still, when your people use heavy machinery, over-protection may prevent them from hearing alarms. Colleagues won’t be able to grab their attention either.

    Realistically hearing protection needs to be a last resort. The best option is to look to reduce the sound levels first.

    For employers, it is their obligation under Health & Safety law to put solutions in place to control noise risks. Preferably, they should minimise noise levels in the workplace. Silencers work well here.
