Low-pressure demand controlled exhaust unit

The ideal solution for ventilation at low-pressure

Specially adapted to 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. Operating at pressures from about 15 to 30 Pa, it can be connected to a low-pressure exhaust fan or to an hybrid fan. In addition to exempting measurement of duct airtightness, the low-pressure operation offers the advantage of consuming considerably less than conventional controlled mechanical exhaust ventilation, with quiet operation.
