The ideal solution to refurbish ventilation while keeping low-pressure operation
Specially adapted to work at low pressure, the GBP humidity sensitive exhaust unit is an ideal solution for the renovation of ventilation ductwork 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 collective 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 a hybrid fan (VBP, VBP+). In addition to making it unnecessary to measure duct air-tightness, low-pressure operation offers the advantage of consuming considerably less energy than conventional mechanical exhaust ventilation, with quiet operation.
