Ultra-Zone Forced Air Zone Motorized Round Dampers, 14" Dia, 16" Length
A single blade round damper with a (2) two position, 24 volt motor. The motor is powered both ways - powered open and powered closed. The motor features LED's that indicate the position of the motor whether open or closed. The LED's are colored RED for closed and GREEN for open. These indictors are a failsafe measure meaning that they will not illuminate until the blade of the damper has gone to its full open or full closed position. The motor is a 3 wire hook-up with a common, a power open leg and a power closed leg. The URD Round Dampers are an Inline Duct damper and have a double layered blade design with an integrated cellular foam sealing gasket. URD Round Dampers are easy to install and come with a 5 year warranty. The URD Round Damper is constructed of heavy gauge galvanized steel. The Nylon bearings and Thermo-Tuff drive shafts insure smooth, quiet operation and provide a thermal barrier to the Motor Actuator. The URD Damper is designed to operate at static pressures up to 1.5” w.c. with minimal leakage. The URD has a 5/8” Diameter Drive Shaft which extends 1.5” beyond the damper and a 10-32 Mounting Stud.
