Rectangular Damper | 8X18 ND MOTORIZED DAMPER SPRING RETURN - NORMALLY OPEN

Model ND-RSD is a rectangular parallel blade damper constructed from heavy duty extruded aluminum with nylon bearings for quiet operation. The Motor Actuator is a 24vac (6watt / 8va) Synchronous motor. It is typically a Power Close / Spring Open construction. The damper can be ordered as Power Open / Spring Close. The Model ND-RSD cannot be field-reversed.

The Synchronous motor can get very warm when energized/stalled for extended time periods. To avoid overheating, do not insulate or encapsulate the motor housing. Doing so will damage the actuator assembly and void the warranty. See reverse side for wiring solutions.
