Balance S Diffuser - NO RING - 100mm

Description
Systemair Balance-S supply diffuser for installation on ceiling or wall.

Function
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.

This device can be used for extract air.

Adjustment
The valve cone is screwed a number of turns clockwise or anti-clockwise so as to achieve the air gap in mm which corresponds to the pressure drop and required air flow shown in the diagram. The pressure drop is checked by removing the front plug and pushing in a suitable test probe.
