When range hoods exhaust air out
of your home, negative air pressure
is created unless the exhausted air is
replaced by fresh outdoor air. Zephyr’s
Make-Up Air Damper is designed to
balance the air pressure in your home
by automatically opening to allow fresh
air in while the range hood is operating.
For use with any Zephyr hood operat-
ing over 300 CFM.
