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.
