An efficient motor

The speed of the V4A’s EC-Motor (Electronic Commutation Motor) is controlled by an electronic card. The motor speed, associated with a special wheel, holds the pressure at 100 Pa to keep the airflow proportional to the variable cross-section of the connected demand controlled exhaust units. This keeps power consumption and noise emissions to a minimum.

Optimised for silence

The high efficiency EC-Motor is mounted on flexible links and is encased in a double-skin envelope: the V4A is totally optimised to work silently, allowing installation inside the dwelling.

User-friendly maintenance

Maintenance is simple because the fan is inside the dwelling: the cover is simply lifted off and the impeller is easy to remove thanks to a patented attachment system. And the electrical part is removable, so the motor can be replaced without removing the fan from its support.

12 VAC output for electrical exhaust units

The V4A fan integrates a 12 VAC transformer to supply up to four electrical exhaust units.
