About This Product

Designed to provide the best technology to equalize pressure between indoors and outdoors, while providing effective ventilation for a cleaner, healthier home. Eliminate gases, smoke or particulates generated from naturally vented combustion devices like a fireplace or water heater. Such a complete and simple solution for automatic and controlled fresh air into the home every time you turn on the range hood. This is an interlocked, synchronized system that installs easily and requires only low voltage wiring to the sensor. Perfect for new construction or retrofit into an existing home.


  • Broan interlocked make-up air dampers provide outside air when required to keep the air in the home fresher by allowing the range hood to operate at optimum levels
  • Universal design works with any Broan range hood to balance indoor air pressure by providing interlocked make-up air without requiring a direct wire connection between the range hood and the damper, instead a sensor is attached to the exhaust duct to detect if the range hood is operating
  • Slave dampers (MD6S, MD8S or MD10S) are interlocked to the main automatic or universal make-up air damper and open in unison for synchronized operation, they close, along with the main damper, as soon as the range hood is powered off, slave dampers can be ganged together to provide a cost effective means to provide for higher volumes of make-up air
  • Interlocked make-up air damper systems meet IRC code requirements for make-up air with range hoods over 400 CFM
  • Interlocked make-up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well-balanced environment
  • Fresh air wall caps are required for use with make-up air dampers

Great aftermarket option that saves $$$
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.

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