Motorized Damper

Details

The MD624 motorized damper mounts inline with the ducting to either the Air King QFAM or FAS units. The lead wires from the unit connect to the included transformer that easily plugs into the receptacle inside the QFAM/FAS unit. The single blade damper with an internal gasket tightly closes off ducting to minimize air leakage. When the QFAM/FAS is energized, the damper automatically opens, then closes when the main unit shuts off.

• Automatically opens when the QFAM or FAS is operating
• Tight sealing damper minimizes any air leakage
• Easily mounts inline with QFAM or FAS unit
• Transformer and lead wire included
• Connection to QFAM requires model QMDB (sold separately)
