The Balance-S is a round supply-air diffuser with an aerodynamically shaped valve cone. The Balance-S performs extremely well with regard to sound level, pressure drop, air flow and self-damping. The Balance-S is installed in a frame or directly into the duct.

Design
The Balance-S is manufactured from recyclable polypropylene and tolerates temperatures up to 100°C. This material also withstands most chemicals in small concentrations. Polyether gasket. The Balance-S is supplied in a white finish which matches RAL 9010.

This device can be used for extract air.
