Broan-NuTone 10" Automatic Make-Up Air Damper - Direct Wire

Providing make-up air for exhaust devices is easy, controlling it is not until now. BROAN Directwire Make-Up Air Dampers, when interlocked with slave dampers, open in unison to provide synchronized operation for kitchen, bath and whole house ventilation products. The MD10T is wired to the transformer, using low voltage wiring, which signals the damper to open and close while the range hood is in operation. The intelligent design options ensure optimum performance in a variety of installations and applications.
