Broan-NuTone MD10TU 10" Universal Automatic Make-Up Air Damper

The Broan-NuTone MD10TU 10-inch Automatic Universal Make-Up Air Damper is an essential part for HVAC systems to provide make-up air when exhaust systems such as range hoods are in use. This damper is fitted with a pressure switch that is capable of sensing when range hood is in operation to allow fresh air into building to counterbalance the pressure. It is designed to fit any Broan range hood and can be installed in new constructions and replacement installations. Advantages include better IAQ, energy conservation through the exclusion of uncontrolled fresh air infiltration, and meeting the IRC code for range hoods.
