KNT air supply valves can be installed in the ceiling, on the wall
or directly in the mouth of a ventilation duct using a dedicated
RML mounting frame. They allow smooth adjustment of
the air exhaust flow rate by rotating the disk closure in the
centre.
The air flow rate depends on the opening ratio, i.e.
the distance between the disk closure distance and 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.
