v2a Acoustic whole-house fan - 2 rooms Discretion and comfort for indoor installation Low energy consumption: only 5.5 W @ 40 m3/h. Constant pressure: fitted to demand controlled exhaust units. Easy to install: flat and compact, directly installed in inhabited space. 12 VAC output to supply electrical exhaust units. Outlet 100 mm in diameter. Inlets 80 mm. The best ventilation is ventilation nobody notices. You will not notice the V2A fan: quiet, easily hidden in a wall cupboard or in the loft space. You will simply appreciate the quality of the air renewal. Installed in apartments or in individual houses, the V2A can connect up to two demand controlled exhaust units located in bathrooms and toilets. As far as consumption is concerned, it is as energy-efficient as it is discreet with its low-consumption EC-motor. An intelligent EC-motor The speed of the EC-Motor (Electronic Commutation Motor) of the V2A is controlled by an electronic board. The motor speed, associated with a special wheel, holds the pressure at 80 Pa to keep the airflow proportional to the variable cross section of the two connected demand controlled exhaust units. This keeps power consumption and noise emissions to a minimum. Installed close to the occupant Easy to maintain: simple yearly cleaning of a filter, easily accessible without tools. Because it is silent and compact, the V2A can be installed directly in the living space, in a wall cupboard, a loft volume, etc. Maintenance is facilitated by its proximity to the occupant, and also by the removable filter, easily reached by opening the lid, with no need of a tool. 12 VAC output for exhaust units with electrical boost airflow The V2A fan includes a 12 VAC transformer to supply up to two exhaust units equipped with an electrically activated airflow.
