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.
