BXC Demand controlled exhaust unit for MEV Humidity sensitive, presence detector and switch versions: modulates the airflow according to the various needs of the dwelling. Airflow ‘+’: possibility of setting the airflow levels at installation: up to + 50 m3/h on the max. airflow. Advanced special versions: CO2, VOC, and remote control versions. A multifunctional exhaust unit to optimise indoor air quality and energy efficiency in MEV applications The BXC incorporates all of the functions one could want in an air exhaust unit: various activation modes, such as humidity sensitive, presence detection, switch, and even CO2 are available to adapt the ventilation to occupants’ needs. The exhaust airflow is automatically modulated, in silent operation. The range of variable airflows can be set at installation to meet special needs, or to compensate for a lack of pressure; commissioning is also facilitated by the presence of a pressure plug, which allows measurement and easy calculation of the airflow. Airflow ‘+’: airflow can be set at time of installation (1) The BXC lets you set the airflow according to the pressure available or to specific regulation requirements. The fixed shutter can be set to 6 positions, with an average step of +10 m3/h (maximum = +50 m3/h). Silent working: silent auxiliary airflow activation. Battery indicator: buzzer to indicate low battery level. Pressure plug to help commissioning (2) Pressure plug: allows pressure measurement to determine the airflow. The built-in pressure plug makes it easy to measure the pressure using a manometer, then calcu-late airflow using a table in the installation instructions. Advanced special versions (3) Easy to maintain: removable shutter case and front cover for easy cleaning. 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 availa
