20 Inch Round Motorized Damper

Description

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 year warranty. The URD damper is constructed of heavy 24 gauge 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” w.c. The UL Listed MA-ND5 Actuator is a 24vac 3 wire power open / power close type rated at 18 “ lbs. 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.
