KPP plastic air valves are made from white PVC and as a result, they are
corrosion-resistant. The air flow rate is adjusted by twisting
the disk closure in and out of the bezel. The opening ratio is
fixed with a locknut.
The carefully designed geometry of the valve guarantees low noise levels.
The KPP air valve is fastened to the ductwork end via a mounting frame.
The KPP valve only needs to be press-fitted in the mounting frame.
