The Model PRD-RD pressure regulating damper is a 1-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.
