RDM Series Zone Dampers

The RDM series of round motorized zone dampers are the industries strongest and most reliable professional zone or sub-zone damper with a commercial rated motor.

Floating Point or Two Position Operation: The RDM series can operate as a three wire floating point modulating damper with power open and power close connections. It is also capable of a single contact switched 2 position operation with 100% open to 100% close or as adjusted by the mechanical stops on motor travel. NOTE: RCS Zone Control panels do not provide modulating outputs.

Super Rigid Barrel: The unique design of the barrel offers extra stiffing beads to assure it will stay round even with the roughest of installation handling.

Energy Efficient Seal: The center bead and blade design coupled with the neoprene seal make these dampers the tightest seal in the closed position, with virtually 99% airflow closure. Adjustable stops allow for minimum closure adjustments.

Motor: Belimo KM/LM series 24VAC Motor. Three wire: Com, Open, Close.

Long Life: These dampers have been tested for over 250,000 cycles.
