10 RSD

Indoor Air Quality & Filters

Model RSD is a round single blade damper constructed from heavy (24) gauge galvanized steel. It has a spring return motor actuator. The 24 volt motor actuator is direct coupled to the drive shaft. It is power closed/spring open (standard). The damper is field reversible from power closed/spring open to power open/spring closed.

The RSD includes a travel limiter to prevent full closure, if so desired. It does not have LEDs or an end switch. The RSD has a double layered blade design with an integrated cellular foam gasket to provide a seal when the damper is in the closed position. The RSD also has a Travel Limiter to prevent the damper from closing 100% if your application requires.
  • Available sizes are 4" - 6" - 7" - 8" - 9" - 10" - 12" - 14" - 16"-18"-20".
  • It can also be purchased as a URD-LF24 (24 volt, 35 in/lbs., spring return) or a URD-LF120 (120 volt, 35 in/lbs., spring return).
