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.
The BXC2 exhaust unit incorporates all the functions one could request from an air exhaust unit. With various activation modes such as humidity, presence, CO2 and VOC for example, the BXC2 exhaust unit automaticaly adjusts the level of ventilation according to occupants’ needs in all situations, all rooms.
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.
