The Nekos Kato is a slim line actuator so can give a more aesthetically pleasing installation. There are a few options the Kato 230v, Kato 253 and Kato 305, and again a range of brackets are available. These are just 2 options of many from suppliers such as Topp, UCS, Mingardi, Windowmaster, Aprimatic and Nekos to name some. Favoured on flat roof vents are linear style actuators such as the Aprimatic ST450 or UCS Max Actuator which are nearly silent and have a higher IP rating usually to protect from rain, dust and impact. Linear actuators are typically more powerful than chain actuators.
