The Envirovent Filterless Extract Fan is a major advancement in extract fan technology and has been designed to deliver the lowest possible maintenance, the lowest long term life-cycle costings and lowest performance/energy costs.
Envirovent's Filterless Extract Fans incorporate the latest patented Cyclone Separation Technology. As the contaminated air passes through the helical front grille it is centrifugally thrown outwards into two helical expansion chambers which allows the air to expand directly out to atmosphere. This unique process quietly takes most airborne contaminants with it out to atmosphere and negates the requirement for filters.
One fan for all situations
From simple through the wall installations to complex ducting/bend systems the Filterless Extract Fan fits all applications with the use of easy to install accessory kits. The Filterless Fan concept has allowed Envirovent to create a product, free from all of the inherent problems associated with traditional extract fans.
The in-line centrifugal impeller with its unique helical power expansion chamber enables the unit to achieve power with efficiency and quietness in the most compact unit ever.
