Damper Specifications
The damper is not required if using a recirculating kit.
The damper is controlled by a pressure switch and independently powered.
It can work with any blower or vent system, including in-line blowers.
It is connected to 120V supply, and the transformer installed reduces the power supplied to 24V.
The damper opens when a range hood is operating. Creating a known, controlled point for fresh air to enter the home while air is being exhausted from the building by the range hood.
When in use, gravity and the exhausted air force the damper open and closed. Dampers provide two key benefits for the home:
Facilitates air exchange between indoors and outdoors, by drawing fresh air into the home to replace exhausted air.
Helps avoid negative pressure conditions within the home, which may interfere with the proper operation of combustion equipment within the home by drawing in the fresh air.
