Acoustic whole-house exhaust fan - 6 rooms


Great capacity and low consumption

Thanks to its slim design and silent running, the VAM whole-house exhaust fan is ideal for installation in inhabited spaces, such as cupboard spaces or ceiling voids. With its powerful motor, the VAM whole-house exhaust fan can be connected up to six exhaust units in the same dwelling. The pressure can be set, during installation, at one of three levels; its characteristics make it particularly well suited to the operation of Demand Controlled exhaust units.

  • Silent: only 29 dB (A)*. Strong soundproofing and control on the motor.
  • Constant pressure: special for demand controlled ventilation.
  • Pressure level, adjustable at the installation: 80, 100 or 120 Pa.

* @ 100 m3/h

  • Low energy consumption: only 23W*.
  • Easy to install: slim design, to be installed in inhabited space (wall cupboard, corridor, etc.).

An intelligent and energy efficient motor

The VAM whole-house exhaust fan is driven by an asynchronous single-phase motor in which the number of revolutions is maintained at a constant rate (within the limits of available power), whatever the airflow required by the exhaust units, thanks to a tachometer and an electronic board. The power is adapted and optimised to limit noise and energy consumption at every moment.

Installation in close proximity to the occupant

The silent running and compact construction of the VAM whole-house exhaust fan make it really easy to install directly in the inhabited space of the dwelling, in a wall cupboard, ceiling void etc. Maintenance is then facilitated by its location within the dwelling.
