Ventilation System VentoAir

Self-regulating mechanical fan for the window rebate – invisible protection from damp in residential properties

Schüco VentoAir regulates the necessary ventilation in residential properties, including dehumidification, without any intervention from users, thus enabling the prevention of expensive damage caused by mould, which is hazardous to health. The principle is based on the equalisation of the difference in pressure between outside and inside. In the process, the action of the fan is purely mechanical. In the event of high winds, the ventilator flap automatically regulates the inflowing air, thus preventing unpleasant draughts.

Schüco VentoAir is installed without screw fixings and almost fully concealed in the area of the centre gasket – either horizontally at the top or in the outer frame rebate at the side. The ventilation system can also be used in conjunction with shaft ventilation systems or for cross ventilation and thereby fulfils the minimum requirements for protection from damp.
