  1. Using silencers to reduce the noise from inline fans
    9 September 2020

    Many buildings have large HVAC systems to provide sufficient heating and cooling. They are important for air circulation but there is a downside to using them. This is the fact that they can be very noisy. The noise can be a big problem in some areas. Luckily, there is a solution. It is possible to create and install an inline silencer to tackle the noise.

    Is it too loud?

    Every HVAC system will generate some noise. Many systems won’t be overly loud and the noise will remain at a safe decibel. However, if the noise exceeds 70dB it can become very harmful.

    The level of noise will depend on a number of factors. For example, the type and size of fan, length of ducts, and location will all have an impact. The size of the room and its acoustics matter too.

    To get an accurate reading of the noise, you will need a dB metre. You should turn the fan on and then test the decibel level in front of the air flow.


    There are a number of ways to reduce the noise from an inline fan. The best option is to choose a suitable silencer. This can fit into the duct and then dampen the noise. It will do this by utilising sound absorption material. The silencers can come in various shapes and sizes so they suit all kinds of systems. We design bespoke ones at Ventx to give our clients the best solutions.

    Other options you can try to reduce the sound include:

    • Soundproofing the whole room
    • Insulating the ducts as well as the fan
    • Muffle the vents
    • Choose a speed controller so you can limit the fan’s rotation

    Talk to us if you need an inline silencer

    If you have a noisy HVAC system, regardless of the type of property, you can rely on us. We have a lot of experience at Ventx and design products for all kinds of needs. Our goal is to ensure every client is happy.

    So, if you need help with an inline fan, please contact us.

  2. Follow the law by reducing the noise
    9 September 2020

    It is no good just leaving industrial noise pollution to run rampant. This form of noise can come from many sources, including a gas vent. What you need is a silencer that can reduce the amount of sound from these vents. Our team can assist you with this by using our modern software to create an effective solution.

    Noise reduction is not only about protecting workers inside industrial facilities. It is also about following the law. One of the most important laws is the Noise and Statutory Nuisance Act. A person’s rights with this Act work in tandem with the Noise Act 1996 and Environmental Protection Act 1990. It can assist those looking to make complaints about large amounts of noise influencing their lives.

    Numerous elements of the 1993 Act are similar to those found in the 1996 Act. This is in relation to the power courts hold to produce fines in addition to other punishments. There are places where they differ somewhat. One is where the Environment Health Department decides whether the sound levels constitute a statutory nuisance or not.

    Statutory nuisances

    So what actually are these nuisances? According to the legislation, the sound that is the source of someone’s complaint has to be detrimental. This is to their health. Alternatively, or at the same time, it has to interfere with someone’s enjoyment on their own land.

    What to do?

    There are those who will want to immediately complain to their local authority. However, another possibility can be to get in touch with those creating the noise. You can discuss the issues with them. This way, you can try to come to an understanding. In the case of an industrial facility, they may be able to install a silencer to limit the noise.

    Let us design a silencer for your gas vent

    At Ventx, we work on behalf of numerous clients in many industries. They all require their own specific model of silencer. Each one has a different design, but they are all effective at reducing noise.

    If you are having trouble with a gas vent and need a silencer, don’t hesitate to contact us. We can design the perfect solution for you.

    Follow the law by reducing the noise
  3. It’s time to start using rotary blower discharge silencers
    9 September 2020

    Our team goes out of its way to help clients to tackle noise pollution in their industrial environments. To do this, we make use of acoustic modelling software to create the best silencers. Designs can include the discharge silencer as well as various other options. Noise won’t be as much of an issue with our help.

    The rotary blower discharge silencers are among the most critical elements if you want high performance. This is within every blower system.

    The majority of people think that the discharge does not produce much sound. They are comparing it to the inlet when they think this. However, it is not true. The high frequency pulsations and discharge sound are recurrent at the outlet. In addition, they can cause the destruction of systems. These are ones working under very high discharge velocities and pressures. The reason for this is that the components tend to be within a closed system.

    Minimising the high frequencies

    There are many benefits to using silencers in these situations. To begin with, high frequency air flow leads to a great deal of vibration and noise. These can be annoying to those in the surrounding areas. The primary job of the silencer is to minimise these high frequencies. They do so by harmonising the pressure surges of the gas that exits the outlet to the open.

    Additionally, silencers work to enhance the efficiency and accuracy of the system. The vibration and noises that occur where you don’t use silencers is a result of the air that passes through a medium. In the process, this typically cools down, resulting in medium imbalances. If you used the medium without it moving through a silencer, inaccuracy problems would pop up. However, you can use rotary blower discharge silencers to resolve this.

    Ordering a discharge silencer

    At Ventx, we work with a very big list of clients. Thanks to our hard work, we can design the silencers that suit their needs. As a result, countless individuals can benefit from a reduction in noise levels.

    If you require a discharge silencer, or something similar, please give us a call. The products we offer are reliable and long lasting. We will also offer advice about upkeep.

  4. The truths surrounding noise-induced hearing loss
    9 September 2020

    Having to deal with loud noises is not only annoying but harmful too. Hearing impairment is just one potential side effect. There are many other physical symptoms that you can experience. Fortunately, we have a solution. This would be to use one of our silencers, like the discharge vent model for instance.

    There are countless individuals out there with hearing loss issues. This might have been caused by leisure activities. More likely, it could have been due to a noisy workplace. The root cause of hearing loss can initially seem straightforward. However, noise-induced hearing loss has several misconceptions surrounding it. We are here to take a closer look.

    Noticing a problem

    Some believe that this hearing loss is noticeable immediately. It is true that numerous people suffer temporary hearing loss following a concert or loud party. However, a damaged ear is something that you may not notice right away. In fact, it could be a problem you only notice in the future when someone points it out.

    It only happens with regular exposure

    Another misconception is that the hearing loss only happens if you expose yourself to loud sounds regularly. One single exposure to a sudden loud noise is all it takes to cause hearing loss. As a result, it is vital to have hearing protection. An industrial silencer can help to reduce sounds at the source too.

    Industrial noise

    Last but not least, there are those who believe that it is only loud music that causes hearing loss. If you are an industrial worker, your profession can be as dangerous as your hobbies. In fact, industrial noise stands as one of the leading causes of hearing loss. This is one of the many reasons why people install silencers in these environments.

    A bespoke silencer for your discharge vent

    At Ventx, we design our products to keep people safe from the dangers of loud noises. We can create a myriad of models to suit any kinds of needs. For example, we have options for vents, fans, machinery, and more. To ensure we design the right one, we use advanced acoustic modelling software.

    If you would like more information about silencers for a discharge vent, feel free to call us. We can discuss how they work as well as the kind of performance you can expect.

    The truths surrounding noise-induced hearing loss
  5. How well do you know blow down applications?
    9 September 2020

    Part of the reason why we are so successful is because we have a long history in industrial silencer design. Thanks to our experience, we can design a blow down silencer that meets all the needs of our clients. We are capable of serving all kinds of businesses, including those who work in petro-chem, gas and oil, and other industries.

    If you want the right silencer, then you need to understand what a blow down application is. We define applications of this nature as where your goal is to expel high pressure gas from a set volume. Usually, there is a final pressure and time constraint specified that is not far from the atmospheric pressure. With silencers, the most common use would be on natural gas compressor pipelines and stations.

    Data requirements

    For a blow down application, there are several pieces of data that you will need. The pressurised volume is one of them. Greater volumes demand bigger silencers.

    You need to know what the maximum blow down time is too. Longer times allow you to use more compact silencers. In emergency scenarios, the total allowable time could be 60 or 180 seconds.

    Lastly, you need to understand the final blow down pressure. You might end up specifying a final one that is under 50 psig. If you do, this shall make it hard to meet the time requirements with economic silencer selections.

    When selecting your silencer, it is essential for you to use the maximum flow rate. You can’t use the average one. If you go down that route, it is going to operate at as much as 2.5 the acceptable maximum velocity for your instrument. This will be the case for the initial 35% of the blowdown cycle. This can lower the lifespan of your equipment. Therefore, you should avoid it.

    Come to us for a bespoke blow down silencer

    At Ventx, we understand how difficult it is to accurately predict noise. To make things easier, we employ modern computer software. This lets us create a model of the noise level that is likely to come from your facility. With the right information, we can create a suitable solution.

    If you require a blow down silencer, don’t hesitate to contact us. We would love to help you to reduce noise on your site.

  6. The handling and storage of silencers
    9 September 2020

    One of the most effective strategies for managing noise is to use silencers. Our company has specialised in designing them for several years. We strive to meet all of our clients’ requirements by creating the finest models. This includes the useful blow off silencer. By working with us to design the right equipment, you can improve performance as well as efficiency.

    Industrial silencers should be able to do their duty continuously within their environment. They should offer free, predicable performance. To ensure this happens, we ensure a professional examines every model we make to check the quality. Then all it takes is the correct installation and suitable maintenance to ensure you will have many great years of service.


    One area where you need to take a great deal of care is with how you handle the silencer. You should only lift it using the mounting supports or lifting eyes. Only personnel with sufficient training should make the lifting decisions.

    Putting silencers into storage

    Some people will only use their silencer periodically. When it is not in use, storing it correctly is important. This is especially true if you are storing it for a long period of time. When you are doing that, you need to ensure it has the right protection. Most notably, you have to keep it safe from moisture and dirt.

    If you use a tarp to cover your silencer, you can keep it dry and clean. Avoid using black plastic tarps though. This will only serve to promote condensation. It is also preferable to keep the silencers indoors when you store them. They will remain safe from the elements this way.

    For silencers installed in exterior locations, you need to safeguard them against moisture. This includes snow and rain. Neither should be able to enter the silencer. Moisture is dangerous since it results in long term damage and negatively influences the silencer’s performance. You can try using rain hoods. Consider screens too to prevent debris from getting in the air stream.

    Let us design your blow off silencer

    At Ventx, we have more than a decade of silencer design behind us. We continue to build on this knowledge so we can offer you the most appropriate model possible. More importantly, our silencers will be practical and cost effective at the same time.

    If you are looking to purchase a blow off silencer or any other model, please give us a call. We can advise you and deliver a model you can rely on.

  7. How natural gas silencers can help
    9 September 2020

    Noise is a by-product in all sorts of settings. However, when the noises get too loud or consistent, it can have negative effects. This varies from physical and mental health problems to lower productivity and more. So, it makes sense to put measures in place to reduce noise where possible. With our natural gas silencers and other solutions, you can do exactly this.

    A little about natural gas silencers

    With natural gas systems, the blowdown needs to generally happen rather fast when maintenance operations are in progress on pipelines. In most cases this will create noise readings that are much higher than tolerable levels. The noise is a result of two phenomena:

    1. The first of these is turbulent mixing. This is the ripping of the air when the vent gas decelerates to zero velocity as it discharges into the atmosphere.
    2. The other is shock noise, which is the instant loss of pressure across a choked flow device.

    However, a silencer can help with the issue. It will control the blowdown and the noise that it creates. The best models have a reactive-absorptive process. This offers great attenuation for all octave frequency bands.

    Silencer designs

    When it comes to the design and selection of natural gas silencers, it is important to keep in mind different factors which will be specific to the application. This includes blowdown time limits, which approach will be the most value for money while meeting needs, performance, and the durability you need for the environment. In addition, you may need an evaluation of natural gas flow and to look at the noise attenuation needs.

    The uses for the silencers includes combustion boilers as well as nuclear and chemical plants. In addition to this, pipelines, and petrochemical and process plants rely on them.

    What Ventx can do to help reduce noise

    Our expert team are able to produce all kinds of solutions to meet various specs. Feel free to get in touch with us if you want to talk more about natural gas silencers. We can also tell you all about how we can supply a solution to suit your needs.

    How natural gas silencers can help
  8. Planning your air vent silencer
    9 September 2020

    The thing to keep in mind about vents is all it takes is for the pressure to be a little higher than atmospheric to cause loud noises. If this happens the sound can seriously harm people on the site. The loudest sounds will also disturb nearby residents, businesses, and wildlife. The solution is to design and install the right air vent silencer.

    Two parts

    The best silencers generally come in two parts. The first is an inlet diffuser. What this does is it provides back pressure and reduces the flow though the silencer. It can also provide some helpful attenuation.

    The second part of the silencer is the absorptive pack. This is a component with perforated steel panels. The holes allow sound waves to filter though. Behind the panels will be some form of porous material that will absorb these waves. Typical substances people favour include glass fibre or rock wool.


    Many people think the inlet diffuser is the least important part of the silencer. Truthfully, some models don’t even have one. However, this can be the wrong design choice. If you don’t include one, the absorptive pack generally needs to be larger so it can provide the attenuation. If size is an issue, it is better to include the diffuser.

    To get the best level of noise reduction, you must have the right perforations in the steel panels. Most importantly they must be the correct size. In addition, it is vital you choose the most appropriate sound absorption material. It is a good idea to consider all the options here and select the right one for your needs.

    On top of this, the silencer must have the right flow passage arrangement. A poor design may put obstacles in the way of the flow. This can result in even more noise. Some people look to avoid back pressure. However, if you choose it properly it can be very useful. Most importantly, it can allow you to use a smaller silencer. It can also reduce the flow velocity.

    Designing your air vent silencer

    At Ventx we know that working closely with clients is essential to producing the right equipment for them. We do just that, getting to know as much as we can about their needs. Then we can use our cutting edge design software to model a silencer that will tick all the right boxes.

  9. The intricate details of vent silencers
    9 September 2020

    To combat loud noises, you need silencers capable of doing the job. Not just any model will do. You need one specifically for your systems. We design steam vent silencer models and other styles. To do so, we use state of the art acoustic modelling software. Every single one we create is bespoke to suit the client’s needs. As a result, you will have a much easier time controlling the noise on your site.

    Many vent silencers are individually designed to abolish noise. Said noises originate from the atmospheric discharges of steam and high pressure gases. You can use a silencer to lower this. What happens is that you install a silencer within the discharge line. Alternatively, it can be at the end of this line. It supplies you with noise limitation while releasing steam or gas.

    Getting the most from your steam vent silencer

    There is a way to get the most out of these silencers too. What you must do is design them so that they use two noise limiting techniques concurrently. These would be reactive and absorptive. In addition, it is preferable to have sound absorbing materials. This is as well as tuned reactive chambers.

    Broadband attenuation

    The silencer’s absorptive behaviour supplies users with broadband attenuation. Reactive behaviours are dictated by a mixture of changes in forced phase shifts as well as flow section. It offers you greater attenuation within the lower octave bands. Each technique makes contributions to greater noise reduction. This is over the whole audible frequency range.

    Noise and gases enter the silencer via compact holes within a diffuser. This provides a weighting-shift that goes towards high frequencies. In addition, a successive expansion chamber offers reactive limiting of the low frequency elements of noise. Acoustic lining that goes to the expansion chamber manages the absorption of high frequency energy. Partially silenced noise and gases head through to multi tubular acoustic models next. Here, there is one last reduction.

    Talk to us to design a silencer

    At Ventx, the silencers we design will benefit you and your workers at your facilities. Furthermore, they are essential to ensure you comply with the UK’s environmental standards. We can offer models that will make sure you get the very best performance.

  10. Which styles of industrial silencers do you need?
    3 August 2020

    Industrial settings can be incredibly noisy. This is largely due to the heavy machinery and systems in use on the sites. Repeat exposure to the loud noises can cause hearing damage and several other health problems in people who work on the site or live near it. To make sites safer, it is important to reduce the noise to a less harmful level. The best way to do this is with industrial silencers.

    The key to maximising sound reduction is using the right silencer in the right location. To do this, you need to know about the different types you can choose from. Below we will have a look at four styles.


    This is probably the most common type of silencer on the market. The style is very popular because they actually feature materials to absorb the sound energy and turn it into heat. The absorptive material can vary in type and thickness to suit different needs. These silencers are very dynamic because you can install them horizontally or vertically in an array of settings.


    The second style of silencer does not seek to absorb the sound waves. Instead they reflect it back towards the source to reduce the amount of noise that escapes. These silencers can be very small because they don’t need to contain any absorptive material. They are also easy to clean, making them a low maintenance option.

    Steam vent or gas

    These models generally don’t seek to absorb the sound or reflect it back. Instead, they look to diffuse the flow of pressurised gases or steam. The high flow and velocity can result in very loud noises. However, this kind of silencer can reduce the pressure and allow gas or steam to diffuse to the atmosphere at a lower velocity.


    As you can probably guess from the name, this type of silencer can combine different elements of various models. Most commonly they are absorptive and reflective to provide the benefits of both.

    Talk to us about industrial silencers

    Ventx is one of the best silencer developers in our field. Our team are experts and have access to fantastic resources such as the latest 3D modelling software. As a result, we can design products to suit any needs.

  11. Sound advice for lowering noise pollution
    3 August 2020

    One of the worst things people have to put up with is noise pollution. To avoid the numerous health issues it produces, the industrial silencer was born. These devices can substantially reduce the amount of noise. With our instruments, you can manage the noises coming from all sorts of machines, HVAC systems, and more.

    A growing concern

    In the world of busy cities and towns, as well as hectic living, noise pollution is becoming more of an issue. The dense traffic does not help matters either. This issue does not produce as many huge health issues as other types of pollution. However, they still exist regardless. They include high blood pressure and loss of hearing. There can also be behavioural and emotional issues, including anxiety and aggression. Knowing this, it becomes evident that noise prevention and pollution control are vital.


    The Control of Noise at Work Regulations 2005 aids us in safeguarding the UK workers that encounter noise pollution. This could harm their hearing. Noise pollution that happens at work can lead to tinnitus and deafness in many UK residents. It can also cause other ear conditions too.

    Under the laws, employers must inform workers in loud locations about the dangers to their hearing. They have to then train someone to introduce a noise programme. Moreover, they have to perform frequent noise assessments. Weekly or daily average exposure could surpass 85 dB(A). If this happens, they must designate the area as a hearing-protection zone. Finally, they must provide suitable PPE.


    Aside from the law, technology can play a part in lowering noise pollution. One solution would be moving traffic from residential locales. Another is installing noise barriers at major roads to deal with the sounds. The design of buildings has taken noise into account too. Many are now built to contain it. Not to mention, car engines are quieter than they once were.

    Then there are the industrial sites. We assist clients here by providing brilliant silencers to keep people safe.

    Design a bespoke industrial silencer

    At Ventx, we spend time designing the most effective silencers for every need. Because of our acoustic modelling software, we can provide you with a suitable product. It will do the job without interfering with the machinery or system you have.

    Contact us today if you want to design an industrial silencer. We will ask you some questions and then get to designing the right product for you.

  12. Silencing safety valves
    20 July 2020

    Ventx is one of the most skilful designers of silencing products in the UK. We can offer solutions for various needs. This includes models for vents, fans, and all kinds of systems. We are also the best place to look for a bespoke safety valve silencer. Every product we offer will be fit for purpose because we put a huge amount of effort into getting the designs right.

    Few components are as important as safety valves. They are the final line of defence in systems that rely on pressure. The idea is, if the pressures in the system rise too much, the operator can open the valve to release it. This can help to prevent total failure, something which could put lives and the property at risk.

    How do they work?

    Safety valves usually have a spring and back pressure to keep them closed. They therefore remain in equilibrium until the system pressure rises to exceed this. When that happens, the valve can open. As a result it helps to reduce the build up of pressure in the system.

    When a safety valve opens it could release compressed air, inert gas, steam, hot water, or even process fluids. This will hopefully bring the pressure down and prevent system failure.

    The valves must be the right size to ensure the pressure can come down. If they are too small the valve will not be able to discharge the excess pressure, meaning it will continue to rise in the system. On the other hand, if they are too large, the high system pressure will not be able to open the valve entirely. This can result in a cycle of opening and closing which will create a chattering noise.

    Use a safety valve silencer

    While they are a potentially lifesaving component, safety valves can be very noisy when they release the pressure. As a result it is a good idea to use a silencer. This can mitigate the noise and improve safety and performance.

    Ventx designs fantastic silencers that will be perfect for your needs. They can be various styles and sizes to suit different needs. This includes being able to address loud discharge noises from safety valves.

    If you want to talk to us about designing a safety valve silencer, please get in touch. We support clients in various industries and offer consistent, high quality silencers.

    Silencing safety valves
  13. Silencing autoclaves
    20 July 2020

    Autoclaves are not a new piece of equipment. In fact, the first steam steriliser dates back to the 19th century. This was when Charles Chamberland, a French microbiologist, found the benefits of using steam instead of open flames. Since then the technique has become a standard in medical facilities, research, and more. While the machinery is useful though, it can get noisy. Luckily, Ventx is here to help and can offer an autoclave silencer to suit any needs.

    What can an autoclave do?

    There are lots of uses for autoclaves. They are the best for applications that require sterilisation as the hot, high pressure steam can kill micro-organisms like bacteria and viruses. As a result they reduce the risk of infection and illness.

    The most common uses for autoclaves are medical, including in the creation of pharmaceuticals, sterilisation of medical instruments, dentistry, and the manufacture of prosthetics. However, they also have use in the veterinarian field, tattooing, and all sorts of labs. In addition, they are good for sterilising medical waste before disposal.

    The machines can come in a variety of sizes, from large ones with huge capacities to smaller units. The difference is usually down to the capacity. The largest models can be hundreds of litres whereas small ones can be less than 100.


    The thing to keep in mind with autoclaves is that they can be noisy. The steam is very hot and at a high pressure. As a result it can cause noise issues, especially with valves and vents.

    There are many cases where the noise from an autoclave is a bad idea. For example it could be a sensitive lab where the sound would disturb people and affect tests or research. Or, it could be a dentists or a clinic where the sounds would affect patients. Whatever the case, reducing the sound is a good idea.

    Choose the right autoclave silencer

    At Ventx we are confident we can design silencers to suit all kinds of autoclaves. Our team have a lot of experience and access to great equipment, including modern modelling software. As a result we can deliver the most suitable products.

    If you want to talk to us about autoclaves or need to create a bespoke autoclave silencer, please get in touch. We can give you the best service as well as exceptional support.

  14. How does a steam boiler work?
    20 July 2020

    Heating and providing hot water in large industrial buildings can be very challenging. Standard boilers may not be up to the challenge, especially if there are lots of radiators and facilities. A great option here is to use a steam boiler. However, using them can cause noise that could become an issue. The solution is to choose a reliable steam boiler silencer.


    Steam boilers are pretty complex, especially in comparison to general gas, oil or electric models. There are two types – shell and water tube. The first has the hot steam flowing through pipes, heating water around them. The latter on the other hand is the opposite and has the water flowing through tubes with hot steam around them. Water tube models can achieve a higher pressure. Shell boilers can produce a huge amount of steam every hour.

    Both models can effectively provide hot water and heat for larger buildings. This is because steam can travel more easily through large pipes than water. It can also reduce the amount of pumps the boiler needs.

    These boilers can last a long time, especially with good maintenance. However, they can be noisy. One important feature is the blowdown. This enables the removal of dirt and sludge from the system. When the valve opens it can be noisy though. The system can also generate noise because of the steam, especially venting it.

    Steam boiler silencers

    If the noise from the boiler is causing issues, you can choose a silencer to dampen it. Ventx can help here, offering a reliable service every time. We design bespoke models to suit each specific system we are working with. That means we can offer the most appropriate solution rather than trying to make a standard model work. The end result is better performance and efficiency.

    You can contact us if you have any questions about steam boiler silencers. We can cater for all types of model and any size. In addition, we can provide ongoing support once the silencer is in place.

  15. Consider the long term impact of excessive noise
    20 July 2020

    If you are having problems with noise, our company has what you need. Industrial silencer design is our speciality. We use our skills to find solutions that will benefit clients. Since loud sounds can impact you in many ways, it will be worth your time to see what we can offer.

    Loud sounds may not directly appear to influence how we feel. However, with daily exposure, gradual effects can start to set in. Such exposure is common in industrial settings. The following are some of the most substantial long-term health problems people may experience due to industrial noise.

    Hearing damage

    We will cover the obvious one first, which is hearing loss. The ear is a sensitive array of compact structures. They work to focus and translate sound waves to your brain. Sound moves inside your ear canal. It then vibrates the eardrum and leads to three small bones vibrating. The cochlear hairs notice this and alter the vibration. It transforms into an electrical signal that’s for your brain.

    Workplaces where there are 85 decibels of unending noise are putting their employees at risk. Ears won’t have the opportunity to heal from temporary hearing loss. What’s more, cochlear hair cells will die eventually. This restricts the level of sound your ears can pass to the brain, leading to irreversible hearing loss.

    The cardiovascular system

    Another issue would be cardiovascular impairment. Frequent exposure to loud industrial noise can cause this. Loud sounds are often a signal to turn your fight-or-flight response on. Since this is the case, daily exposure begins this activation. Since this is the case, it can place stress on a fast-beating heart.


    The most important thing to keep in mind is that noise is a stressor. Loud industrial noise can stimulate the nervous system and cause the release of hormones that cause stress. People can struggle with several illnesses linked to too much stress. It can also affect concentration, make people feel tired, and affect the mood.

  16. Top methods of industrial noise reduction
    20 July 2020

    The noises that come from industrial facilities can cause an array of issues. Firstly, the sound can affect people on site. This could harm their health, wellbeing, and performance. Secondly, the sounds can disturb people nearby, whether it is homes or other businesses. Thirdly, the issue can harm wildlife in the area. With all of this in mind, it is important to have a serious look at industrial noise reduction.

    There are a number of different ways for facilities to reduce noise. Ventx has a lot of knowledge of many of them as a leading producer of silencers. We want to take a quick look at some of the top methods you can use.


    One of the things you can do is install damping to help improve the soundproofing. You can install materials on walls, floors, ceilings, chutes, tanks, panels, and more. The goal here is to make it harder for noise to escape as well as reduce the volume of the noises that do.


    You have a number of options to reduce the noise that comes from loud fans. For example there are different silencers to choose from. You can also change the layout to remove anything that might disturb the airflow and cause noise. It may be a good idea to ensure the fans can work at their peak as well.


    Ducts can be very noisy and also create an issue because there needs to be openings to install them. This can allow more sound to escape from the facility. What you need to do is fit silencers to the ductwork and seal it, especially around openings in walls and other surfaces. Both of these can block noises.

    Pneumatic exhausts

    Noise from these can be really loud. Luckily you can fit silencers to reduce it dramatically. You can choose a silencer to deal with noise from back pressure as well as the release of air.

    There are many other things you can also do to reduce noise. This includes replacing pneumatic nozzles for quieter ones, getting quiet modern motors, and changing chain and timing belts.

  17. Why is air venting important?
    20 July 2020

    Many industrial processes rely on cooling to remove heat from equipment and systems. These cooling solutions can including heat exchangers and steam vents to help dissipate the heat. They can also include an air vent so it is possible to remove any air or non-condensable gases. The issue is the vents can generate a lot of noise. The team at Ventx can help with this. We have the skills to develop a steam vent silencer to suit any system.

    The issues

    The presence of air and non-condensable gases in a distribution network or process equipment can cause a number of problems. Most significantly, it can affect the performance and how efficient the plant is. On top of this, it can increase the start up time. So, the solution is to vent the gases so they are no longer in the system. However, it is important to get the venting right.

    If the air venting is not effective or not done at all, it can cause a number of issues. For example, it can hit productivity by reducing the heat transfer rate. Even a thin layer of air can insulate a heat exchanger and make it less effective.

    In addition, the air and other non-condensable gases left within a system can cause higher corrosion. This can lead to more wear on components in systems. With enough time it could even result in unexpected failures.

    Other issues include malfunctioning traps as well as a reduction of the steam pressure. It is wise to use traps with air venting to protect their performance and reduce issues.

    Steam vent silencer

    While air venting is important, it can be noisy. Luckily, Ventx can help by creating bespoke silencers. They fit directly on to the vents and have absorptive material to ensure effective silencing.

    If you need a steam vent silencer or any other model, we can create it for you. We have great resources, including top of the range 3D modelling software. As a result, we can get a better idea of important things like the fit and performance we can deliver.

    Speak to us today to discuss the benefits of silencing and why our equipment is the perfect option for you.

  18. Why we need noise control in harsh work settings
    20 July 2020

    Efficient noise control is something we work hard to help our clients achieve. For this to happen, we use acoustic modelling software. This helps us to design and manufacture the ideal silencers for everyone. It could be a HVAC system, a loud steam vent, a huge industrial fan or noisy machinery, whatever the need, we can provide a solution.

    In every single workplace it is important to consider the acoustics. The last thing you want is to leave your team working in a place that is too noisy for them to do their job. This can also be detrimental to their health and wellbeing.


    In industries like offshore oil and gas it is even more important to address the loud noises. This is because personnel live and work in the area and can’t escape the sounds. Exposing them to the noise for long periods can be really harmful to them.

    Managing the noise is beneficial for more than the wellbeing of employees though. For starters, it makes communication easier and can boost performance too. Being able to communicate effectively is important in such dangerous settings. If it is so loud your employees can’t hear each other, machinery, or even warning alarms, there will be more risks.

    Moreover, employees that reside on site need to be able to rest and relax when they are not working. This can improve their productivity and efficiency. If it is so loud they can’t sleep or unwind in their spare time, you can find more issues with illness and focus.


    Noise pollution and its effects also cause many problems for habitats. As a result, sound regulation is crucial for preserving healthy and safe wildlife. Many businesses will be capable of anticipating issues of this nature. They need to address their corporate responsibility. They need to tailor their initiatives to the wellbeing of animals and humans alike.

    Reliable noise control

    At Ventx, we help people to tackle the issue of noise through the use of our silencers. We match them to the application our team is currently dealing with. Therefore the silencer can serve your needs without compromising any of your other systems.

    If you would like talk to us about noise control and what we can do, please give our team a call. We are an expert team with access to wonderful resources. You won’t find a better partner if you need to tackle noise issues, even in harsh work settings.

    Why we need noise control in harsh work settings
  19. How close are workers and homes?
    20 July 2020

    High levels of industrial noise can cause a lot of problems for workers on a site and people who live nearby. With this in mind it is important to choose the right silencing solutions. These can help reduce sounds sufficiently to ensure operations don’t harm people. At Ventx we have a lot of experience in this area. As a result we can supply a diffuser silencer or any other model to suit a variety of requirements. This includes vents, fans, and loud machines.

    Location has a big impact on silencer design

    A number of different things can influence how much you need to reduce the noise in your facility or on a site. Perhaps the most important is how close people are. If you have people working near to a vent you will need to do more to reduce the noise so employees are not regularly exposed to loud noises. The same applies if the vent is close to a boundary and any housing.

    In both cases above the only option may be to design a large silencer. As a result you can make sure it has the capacity to absorb or diffuse a lot of the noise. You need to plan for this size to ensure you will be able to fit the silencer into the system.

    There will be many other cases where your vents are in out of the way locations. If there is nobody working close by and no homes in the vicinity, you may not need to reduce the noise as much. Here a smaller silencer could be all you need. However, you must think about how far the sound can travel and the possible environmental impact.

    Diffuser silencer specifications

    At Ventx we can design silencers to cater for almost any kind of specifications. For example we can offer large high performance models for vents close to working platforms and busy parts of sites. We use cutting edge software to design these products. This gives us a better idea of how they will fit systems and what kind of performance they can offer.

    If you have a good idea of what type of diffuser silencer you need or want info about the various models you can choose, we can help. Just get in touch and tell us about your needs. We can then offer advice and begin designing for you.

  20. Acoustics means more than you think
    20 July 2020

    Many of us have had to endure the pollution that industrial noise brings. Fortunately, businesses can do a lot more to reduce the sounds and disruption. Thanks to our silencer designs, we have solutions for each situation. This includes the in-line silencer. We are able to create all of these effective tools using our acoustic software. As a result they will be more than up to the job.

    When you think about the word acoustics, what comes to mind? For most people it might be musical instruments. However, one definition of it is the science handling the reflection, transmission, reception, control, and production of sound.

    As you can see, acoustics is a much broader term than most people think. If you are struggling with loud noises from a local manufacturer or even a neighbour, it is likely acoustics are to blame as well as the volume. Luckily, acoustic engineering can have the answer in many ways.

    It is all about vibration and sound

    This form of engineering is a branch that focuses on vibration and sound. Normally, the engineers here concern themselves with noise management. Careers in this area typically involve considerable understanding of maths and physics. Furthermore, you would need a degree that focuses on an engineering discipline.

    Noise control

    This is one of the areas of acoustical engineering, hence why we are talking about it. The goal here is to suppress sound. This could be to enhance the quality of life of people on the site or nearby, or to meet environmental standards. Noise pollution is an increasing issue. This has motivated people to come up with solutions for reducing it. This typically happens through the use of silencers like ours.

    Do you need a bespoke in-line silencer?

    At Ventx, we know how important it is to design the right solution for each noise issue. Were you to put just any old silencer in a facility, it could undermine the systems already in place. This would cause more bad than good. It could even have the opposite affect and make the noises louder. With our help though, you can avoid this.

    If you require an in-line silencer or something similar, please contact us. We will do all we can to design a product that works for you. The acoustic modelling software ensures we get it right and also gives us more flexibility in terms of the design.

  21. Make sure you’re aware of the effects noise can have
    20 July 2020

    Control of noise pollution is necessary in order to ensure the well-being of everyone around. There are also requirements from authorities including legislation that mean you need to keep internal and external noise levels in check. Therefore, you should invest in a vent silencer. This way you will not have to worry about the impact that noise is having on you, the workers in your facility, anyone near the site, and the environment.


    Noise can have a big impact on your sleep and cause lots of health issues. Loud noises can wake you up and persistent sound can cause stress that prevents you from falling to sleep. This then has an impact on your health, including more fatigue, altering moods, and disrupting the functions of your body.


    Your ability to hear is an incredibly important sense as it enables you to be more aware of the things around you. However, you need to keep in mind that your ears cannot handle excessive noise. A single loud sound can cause a lot of damage. In addition, exposure to excessive noise over time can cause hearing impairment or even hearing loss in the future.


    Your ears have an important connection to your brain as they work together to make your body respond to things. So, any noise your body is around will result in messages being sent to your brain so that you know what to do about it. There can be a negative impact on brain functions when there is a lot of noise, including slower responses.

    Get a vent silencer to help with noise pollution

    We can help you get a silencer that is suitable for your specific application. Our team of experts know all about the different requirements our clients may have. As a result we can design the perfect solution.

    Ventx recognise that noise control is a key element in an industrial setting. We can cater for this by offering a suitable vent silencer or other silencing equipment. So, contact us today to start working with our team.

  22. What type of attenuators do you use for a HVAC system?
    20 July 2020

    Our company has a long history of providing its customers with sound reduction devices. These are ones to reduce the level of noise in industrial environments. This includes our attenuators as well as many more models. With more than ten years of experience in industrial silencer design, we can help you meet all your needs.

    Two types

    One of the main systems that typically require an attenuator is the HVAC system. In order to silence these, you would use one of two forms of attenuators. These are the rectangular and circular models. With the former, you fit them into the ducts to minimise sound from the inside. With rectangular ones, you fit them over the HVAC system. Both varieties employ the same principle with limiting noise in these systems.

    Rectangular models come with dissipative silencers. They dissipate acoustic energy that is in contact with the sound absorbing media within. As for the circular attenuator, it has a head, which spins. There is also a tail in a cone shape. Another interesting fact about the circular model is that it is double walled.

    Sound absorbing insulation

    Within the interior wall, you will discover the sound absorbing insulation. This is what helps to keep the noise to a minimum. These attenuators do lower noise. At the same time though, they preserve the pressure changes within the HVAC apparatus. By doing this, air can easily flow through the system.

    You use noise attenuators as one wholesome component of the HVAC system. This is as opposed to having them in isolation. The result is superior performance. It is best to use them when you are installing the system instead of adding them in later.

    Talk to us about attenuators

    At Ventx, offering first rate silencers is one of the fundamentals of our company. One more thing that is equally important, if not more so, is customer service. The demands of customers vary with each new job. Since this is the case, we opt to make ours a bespoke service. This way, we can meet your needs with ease.

    If you would like to do business with us, please get in contact.

  23. The velocity profiles of silencers
    20 July 2020

    When you are dealing with loud noises in an industrial setting, you need the assistance of a company that knows what it is up against. Our team has been specialising in this area for years. Using their skills and knowledge, as well as our high quality equipment, we can create an attenuator that meets your specific requirements.

    Proven designs

    As time has progressed, silencer experts have come up with some rather standard silencer geometrics. These help us in handling the pressure drop vs insertion loss equation. Backed by development and testing, you can apply these designs on an application specific basis.

    You need to choose the right unit for your project. This helps you to obtain the necessary acoustic performance at an acceptable installed pressure drop. You label these designs based on a particular velocity profile. However, you can apply them to an extended array of velocities. You can do this when considering a suitable pressure drop.

    Low velocity

    This is just one of the models you can find. It is also possible to view this as the high pressure drop design. The geometry here offers you an incredibly high degree of acoustic performance. Be careful when the velocities go beyond 100 FPM though. At this point, the pressure drops start becoming inappropriate for the majority of applications.

    Medium velocity

    Of all the designs, this is the greatest all-round performer. Thanks to its straight through parallel entrance, there is huge insertion loss. The tapered tail discharge functions by keeping those pressure drops as low as they can.

    With such a model, you can work your way through all sorts of applications. This includes those ranging from 0 to 2,000 FPM. For most applications, there is going to be a decent amount of pressure drop.

    Order an attenuator from us

    At Ventx, we go out of our way to design your attenuator in the right manner. This is the only way for them to work correctly without compromising your system.

    We have done business with an exhaustive list of clients so we are confident in our ability to help everyone. If you need us for anything, you are welcome to contact us.

  24. Handling the problems associated with air induction systems
    20 July 2020

    Noisy environments are not the best places to work in. However, we all have to make a living and it is tricky to avoid loud noises in many cases. If you are wondering what the solution here is, it would be to work with our team. We can create silencing equipment specifically for your premises. This is something we do using cutting edge software. The model could be that of an intake silencer or a different style. It all depends on you.

    There are those who need to employ a large gas or diesel-powered two/four stroke turbine or engine. Equipment like this draws huge amounts of air into the gear. This is for the sake of combustion. Air induction arrangements of this nature could be aspirated naturally. Alternatively, it is possible to use compressors or turbo chargers to amplify the air pressure being fed into the cylinders or air chambers used for fuel mixing. This increases performance or efficiency.

    The air’s speed

    The speed of the air that rushes inside can create a huge level of noise. Furthermore, the compressor’s or turbo charger’s high rotating speed might cause the sound to radiate. It can do this through the intake filter and down the induction pipe. The noise can therefore end up out in the atmosphere. The compressor or charger will be linked upstream directly in relation to the intake position.

    It is possible to get your hands on a solution using numerous types of rectangular or annular intake silencers. You can have these made to a suitable size so they match the attributes of the flow system.

    Design an intake silencer

    At Ventx, we have a team with more than a decade of experience in silencer design. Using this knowledge, we serve the requirements of various industries. In addition, we make it a point to stay flexible. We do this because we are fully aware that the needs of an individual can vary.

    If you require an intake silencer or something else, please get in contact with us. We can design the perfect product for you then manufacture and deliver it.

  25. The best way to use the in-line silencer
    20 July 2020

    Working in a noisy environment can be more than just annoying. In fact, it can hurt you physically and mentally. Our silencers are here to change that. If you need us to, we can provide you with an in-line silencer capable of lowering the sound your facility creates. We are able to design and supply a wide variety of other models as well.

    What are in-line silencers?

    A silencer of this nature is a pressurised model focused on lowering the noise from compressors and valves. In order to produce a suitable design, you must have extensive engineering knowledge. In addition, you will require accurate quality processes and sufficient field experience. The result will be safe products that offer high performance.

    It is possible to lower the noise that compressors or control valves generate in pipes using these silencers. Of course, you must insert them into the pipe in the right way.

    The best approach to take would be to fabricate silencers with special materials. These are ones that can absorb sound in pressurised settings. They will not be exposed to the flow directly. This kind of set up allows for greater velocities when you compare to regular sound absorbing materials. In the end, you will be able to preserve the higher initial acoustic performance.

    Think about the diameter variance

    With in-line silencers, they are properly flanged downstream as well as upstream of the pipe. The pipe’s sizing seldom enables someone to insert a silencer without considering certain details. Among these is the diameter variance. It is necessary to enlarge the diameter to guarantee internal speed control.

    When the source of the noise is a control valve, you should install the silencers close after this valve. Doing so will allow it to absorb the sound energy the moment it is generated.

    Talk to us to design an in-line silencer

    At Ventx, we make it a point to design our merchandise in the right ways. This way, each silencer can function properly. The existing system won’t end up compromised.

    If you need our help to create an in-line silencer, please let us know. We can discuss your system and the kind of solution you need.
