4 Different airflows in 1 design
Thermally broken self-regulating aluminium vent, suitable on aluminium, timbre and uPVC windows. D ue to its unique patented inner mechanism, 4 different air flows of 54, 67, 7 7 & 101m3/h/m can be reached, while maintaining the full range of control. From aesthetical point of view different AR75 (with different air flows) can be installed in one facade while maintaining the same look .
The self-regulating flap reac ts automatically to var ious wind pressures thus preventing draughts and saves on energy costs for the end-user. The inner flap, which ac ts as an insec t mesh, is easy to take off for maintenance pur poses.
