The URD series of round motorized dampers are a double layered blade design with an integrated Poron sealing gasket. The superior design insures long life and zero maintenance. URD dampers are easy to install, easy to wire up, and come with a 5 years warranty. The URD damper is constructed of heavy 24 ga galvanized steel with factory rolled stiffening beads. The nylon bearings and ThermoTuff drive shafts insure smooth, quiet operation and provide a thermal barrier to the motor. The URD is designed to operate reliably at static pressures up to 1.5 in WC. The UL Listed MA-ND5 Actuator is a 24 VAC 3 wire power open / power close type rated at 18 Inch-lb of torque. It includes an integrated wiring terminal block, and a NEMA1 rated housing. The MA-ND5 motor features bright green and red LED's which correspond to the OPEN and CLOSED position of the blade. The motor also includes adjustable End-Stops for Min/Max blade position, that allows for field balancing of the full or minimum CFM flow, into a particular zone or area. The position LED's will illuminate regardless of the end stop positions.
