The URD series of round motorized dampers features a double-layered blade design with an integrated Poronâ„¢ sealing gasket, ensuring long life with zero maintenance and minimal leakage. Constructed from heavy 24-gauge galvanized steel with factory-rolled stiffening beads, these dampers are easy to install and wire. Nylon bearings and ThermoTuffâ„¢ drive shafts provide smooth, quiet operation and act as a thermal barrier to the motor.Designed to operate reliably at static pressures up to 1.5" W.C., this damper includes a UL Listed MA-ND5 actuator (24 VAC, 3-wire, power open/power close) rated at 18 in-lbs of torque. The motor features bright Green (Open) and Red (Closed) LED position indicators, an integrated wiring terminal block, a NEMA1 rated housing, and adjustable end-stops for field balancing of minimum/maximum airflow.
