34x14" Shutter damper with spring-return actuators, 24V
Item #: 95752
EFD Shut-off damper for rectangular ducts
EFD is a shut-off damper. The damper is provided with 24 V motors with spring-return actuators. The EFD conforms to leakage less than 1% of the local design airflow rate at the local maximum static pressure. The outdoor/exhaust air damper prevents the hot water coil from freezing and also prevents the cold air from cooling down the building if the unit stops.
The EFD multi-leaf damper comprises a number of opposed blades, swivelling on nylon bearings in a sheet metal framework. The blades are connected via a system of linkages (protected) on the outside of the frame.
