Description
The RRD is a round damper that is easily inserted into rigid round ducts for retrofit zoning in forced air heating and cooling systems. It is available in four sizes for use in 5”, 6”, 7”, and 8” ducts.
The damper is used with Honeywell Home TrueZONE panels and similar zone control systems. The power open, power closed actuator draws 2.5 VA allowing multiple dampers per zone, but delivers high torque for reliable operation.
