V4A Premium

Acoustic whole house fan - 4 rooms

Silent operation and efficient ventilation for the whole dwelling

The V4A fan has been designed to ventilate a complete dwelling, with up to four extract units located in the kitchen, toilet(s) and bathroom(s). Easily hidden in a loft space, cupboard or ceiling void, the V4A will provide you all the comfort and air quality you can expect from a low consumption, silent fan.

When installed in an apartment or individual home, maintenance is simple thanks to its location inside the dwelling. The new Premium version has an impressive specific fan power of a little as 0.26w/l/s. The ECM motor (Electronic Commutation Motor) of the V4A is driven by an electronic card which controls the speed. The motor speed allows the pressure to be maintained at around 118 Pa (max), with the airflow proportional to the variable cross section of the connected humidity controlled extract units.
