The technology behind the Filterless Fan EnviroVent’s Filterless Extract Fan ensures that all particles, humidity and dust in the air are drawn into the fan and extracted outside the property, without the need for filters that can become clogged. This enables the fan to deliver the maximum of performance to control moisture and humidity using the lowest energy consumption. 1 Air is drawn through the front grille 2 Air flows through the easy clean impeller 3 Air is thrown outwards through a dual powered expansion chamber and allowed to expand out to atmosphere 4 A ir is expelled through robust rear carcass Intellitrac ® vapour tracking Running continuously on trickle, the Filterless Fan ensures that condensation and high humidity levels are kept at bay. No user intervention is required as the intelligent vapour tracking controls constantly monitor the humidity level. As this rises and falls, the motor speed rises and falls in direct correlation. This controls condensation both quietly and efficiently, eliminating the problem of noisy extract fans and reducing the periods of time when the fan operates on maximum speed, saving energy.
