Equalized Air Pressure For A Well-Balanced Home (and budget)
Providing make-up air for exhaust devices is easy, controlling it is not - until now. Broan Automatic Make-Up Air Dampers are the first to provide synchronized operation for kitchen, bath and whole house ventilation products. Installation is simple and requires no special wiring. The intelligent design options ensure optimum performance in a variety of installations and applications. Highly effective and affordable, the Broan Automatic Make-Up Air Dampers strike the perfect balance to keep you and your home breathing easy.

The Broan line of make-up air dampers removes the unnecessary energy cost penalty from the equation. Broan Make-Up Air Dampers operate only when it is necessary to let compensation air into the home. This is accomplished by the SmartSense fans and/or selected BEST or Broan range hoods communicating with the Broan Make-Up Air Damper when it is time to open and let compensation air into the home.
