SD regulation damper

The SD butterfly regulation damper is suitable for installation on circular diffusers, it is made of galvanised steel and it comes with a sturdy adjustable opening/closing mechanism, which prevents vibrations and noise.
The damper is adjusted by turning the adjustment screw using a screwdriver, by inserting it into the hole on the threaded bar of the diffuser.
