8 Inch Round Motorized Spring Return Damper
Model RSD is a round single blade damper constructed from heavy (24) gauge galvanized steel. The 24 volt motor actuator is direct coupled to the drive shaft. It is a power closed/spring open action. (standard). The damper can be field reversed to a power open/spring closed action. The RSD has a double layered blade design with an integrated Poron® 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. Note: 18” and 20” RSD models utilize a Belimo TF series actuator for increased reliability. The hysteresis motor can get very warm when energized/stalled for extended time periods. To avoid overheating, DO NOT cover/encapsulate or insulate the motor housing. Doing so will damage the actuator assembly.
