AIR-IN® CHAMELEON FRAME VALVES
The Air-In® Chameleon frame valve is a sophisticated Finnish supply air valve installed in the frame.
The Air-In Chameleon frame valve consists of the Chameleon valve, a silencer unit and an outer grille. The valve automatically adjusts the nozzle opening according to the underpressure in the apartment. It also effectively prevents any backflow of air.
Features
- Installed on the window frame.
- Efficient backflow prevention as a standard feature, preventing any flow-through of air.
- Effectively reduces noise from the outside. See table below. The valve produces some 7–8 litres of draught-free air guided up and to the sides without causing a feeling of draught.
