Adjustable airflow at installation

The BXC exhaust unit offers a range of possible airflow settings to meet specific needs, or regulatory requirements. The fixed shutter can be set at one of six positions, with an average step between each setting of + 10 m3/h (maximum = + 50 m3/h). This can, for example, be very useful to compensate for a lack of pressure.

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. These innovations are especially well suited to applications in schools, offices, gymnasiums, mobile homes, etc. A remote control version is also available.
