Electric Window Actuators for Home & Commercial Use
Electric window actuators, also known as electric window openers, are increasingly popular for both home and commercial use. Our range includes robust products like the Topp ACK4, which features an adjustable stroke and versatile brackets, making it ideal for schools and commercial settings.
For skylights we favour the Kato Actuator as the perfect bracket to fit to a Velux of Fakro window allowing a cheap retro fit option.
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.
