Best 10" Automatic Make-Up Air Damper - MD10T

Providing make-up air for exhaust devices is easy, controlling it is not – until now. BEST® 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 option s ensure optimum performance in a variety of installations and applications.


  • Interlocked make-up air dampers provide make-up air when called for to keep the home comfortable by allowing the range hood to operate at optimum levels
  • Directwire design works with select BEST® range hoods to balance indoor air pressure by providing interlocked make-up air; damper opens automatically when fans are activated
  • 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

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


from North Little Rock, AR, USA

Comments about Best 10" Automatic Make-Up Air Damper:

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.
