COMPAIR®flow Star - Blower-Door-Zertifikat
The airtightness achieved in the blower door test reduces the heat loss almost to zero when the extractor hood is switched off.The energetic quality is drastically improved, because the flap has the same high tightness in both directions (negative pressure and positive-pressure measurement).
Can be used for CRV-operation (controlled room ventilation with window switch, which ensures that the extractor hood fan only runs when a window is open) and energy efficient homes. Pays for itself after a few years through energy-efficient operation based on reduced heat loss.
Ideal for retrofitting in the context of an “energy check” in connection with the COMPAIR® flow flat duct system.
