Features

Providing make-up air for exhaust devices is easy, controlling it is not - until now. BROAN Direct wire 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.

Purchased this during a kitchen remodel when we determined that we needed a make-up air duct.  We had purchased a Thermador Hood for our kitchen when we realized it likely was going to pull out to negative pressure in the home.  This has worked great with the pressure switch that automatically opens the damper when the pressure builds in duct.  Only had a problem with the pressure sensor on install, found out quickly from tech support that it can only be mounted upright, we had not.  When I corrected that, it functioned as it was supposed to.

Great aftermarket option that saves $$$

broan-nutone.com

Found a single MD10TU and 10 inch duct without a fan behind it insufficient to adequately compensate for an 800 CMF vent fan. 

The damper stays in the open, (powered) position with the vent fan off with no back draft issue present. A replacement pressure switch in on the way.

MD10TU used in make-up air duct for 800 CFM Broan in-line Vent Fan
