Flush-mounted exhaust unit: discreet and non-intrusive

Humidity sensitive, presence detector and switch versions: modulates the airflow according to the various needs of the dwelling

Advanced special versions: CO2, VOC, and remote control versions

Silent working: silent auxiliary airflow activation

Battery indicator: buzzer to indicate low battery level

Easy to maintain: removable shutter case and front cover for easy cleaning


Airflow ‘+’

Airflow can be set at time of installation to meet specific needs, or to compensate for a lack of pressure. The fixed shutter can be set to 6 positions, with an average step of +10 m3/h (maximum = +50 m3/h). It allows the airflow to be adjusted according to the available pressure or specific requirements.

Pressure plug to help commissioning

The built-in pressure plug makes it easy to measure the pressure using a manometer, then calculate airflow using a table in the installation instructions.

Advanced special versions

The BXC was the first exhaust unit in the world offering the possibility of having built-in CO2 and VOC sensors, for example. In keeping the same innovations, the BXC-EG is especially well suited to applications in schools, offices, gymnasiums etc.

(1) Default setting.
(2) Tolerance : 13m3/h +/- 3  ,  80m3/h +/- 10.
(3) Airflow ‘+’: the airflow can be increased from +10 m3/h to +50 m3/h (6 positions available). This function can be used to adapt to lower pressure or to specific regulations imposing higher airflows. Standard is position 0 (minimum airflow = 12 m3/h @ 100 Pa).
