3 Wire RDM Series Modulating Dampers
The RDM series of HVAC Zone Dampers are round motorized dampers which allow for variable damper blade positioning for MODULATING zone airflow. The RDM series of round motorized zone dampers are the industries strongest and most reliable professional 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.
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.
