The Envirovent Filterless NB Fan is our recommended extract fan for mould and condensation problems in private and rental houses. We recommend using the Envirovent Filterless NB fan as part of a dMEV system to achieve a constant whole house ventilation rate with boost extraction when needed. The Envirovent Filterless NB fan can also be used for a stand alone fan in a bathroom or kitchen.
Envirovent’s Filterless Extract Fans are the only fans with patented Cyclone Technology. This 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. Integrated within the Filterless Extract Fan are the unique Intellitrac® humidity tracking controls, which constantly monitor the humidity level. As humidity rises and falls, the motor speed rises and falls in direct correlation. This controls condensation quietly and efficiently, eliminating the problem of ‘nuisance running’ and reducing the periods of time when the fan operates on maximum/boost to save energy.
From simple through the wall installations to complex ducting/bend systems the Envirovent Filterless Extract Fan NB will deliver the performance to meet building regulations and beyond
