A multifunctional exhaust unit to optimise indoor air quality and energy efficiency in MEV applications
The BXC² incorporates all of the functions one could want in an air exhaust unit: various activation modes, such as humidity sensitive, presence detection, switch 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.
Battery indicator: buzzer to indicate low battery level.
Pressure plug: allows pressure measurement to determine the airflow.
Easy to maintain: removable shutter case and front cover for easy cleaning.

Adjustable airflow at installation
The BXC² 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.

(1) Default setting.
(2) 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).
(3) Delivered in specific versions or available as accessory (ref. AEA317).

The TDA exhaust units directly adjust the extracted airflow to the level of human presence detected in the room. The airflow level in “presence” mode can be adjusted at every moment according to the usual number of occupants in the room (1 to 4 persons per vent).
By adjusting the airflow to the ambient relative humidity rate, the GHN humidity sensitive exhaust unit is the perfect solution for the natural ventilation of wet rooms. Directly replacing the old exhaust unit without modification of the hole, it fits perfectly into the environment of bathroom, toilets and kitchen. Its robust and reliable humidity sensitive sensor ensures optimum performance at all the times, with remarkable longevity.
Specially adapted to work at low pressure, the GBP humidity sensitive exhaust unit is an ideal solution for the renovation of ventilation ductworks initially operating in natural ventilation. The GBP exhaust unit is available in several versions activated by a humidity sensitive sensor or by a pull cord, for implementation on shunt or individual air ducts.
