Hybrid working: allows natural ventilation when stopped / at very low speed.


Not critical: ensures natural ventilation if the fan stops.


Low energy consumption: only 35 W at 800 m³/h @ 20 Pa.


Constant pressure: adapted to demand controlled ventilation.


Fire safety: can withstand hot smoke up to 400°c for 30 mm.


Adapts to weather conditions: management system (ms version) with temperature sensor.


Renovation or new building, on natural ventilation ductwork.


Alarm output (ms version).


Low maintenance: low air speed = lower dusting.

Patented smart blades design

The unique smart propeller design of VBP+ prevents from creating pressure loss when stopped: the central blades are parallel to the airflow, the airflow being generated through static peripheral paddles. Thus, the system is not critical in case of supply failure (natural ventilation working mode). The C4 version offers a galvanised steel propeller; the R version is equipped with a plastic one.

Fire safety

The VBP+ fan range offers a very high level of fire satefy: thanks to body and structure in galvanized steel and their patented design, the R version and the C4 version enable to extract smoke up to 400 °C, at their nominal airflow, during 30 minutes. Thanks to the non-combustible matrix made of calcium silicate protecting the motor, the C4 version can still operate to fire smoke up to 400°C, at least during 30 minutes.
