EWC Controls 30X24 ND-RSD NC Motorized Damper Spring Return - Normally Closed
General Features:
The 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 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.
