Pressure Regulating Bypass Damper
|Air Flow Capacity (CFM):||
Model PRD-RD pressure regulating damper is a single blade, round variation of a barometric relief damper. This is the simplest, most economical way of bypassing excess static pressure in multi-zone applications. Resistance is controlled by offsetting the arm and adjusting the weights. The arm can be inserted into either side of the damper for added versatility.

Comments about 12" PRD-RD Pressure Regulating Bypass Damper:
It is a pretty good damper; is has a rubber collar around the "door", so it works silently and it is air tight. The damper's arm can be mounted to either side of the damper - no problem if you have access to only one side of the damper. The damper has good finish and made from heavy duty steel.
