KN air supply valves can be installed in the ceiling, on the wall
or directly in the mouth of a ventilation duct using a dedicated
RM mounting frame. They allow smooth adjustment of the air
exhaust flow rate by rotating the disk closure in the centre.
The air supply flow depends on the disk closure distance from
the round bezel and it is set with a locknut.
The carefully designed geometry of the valve
guarantees low noise level as well as quick and easy installation.
