Broan MD8T Reviews

Rated 5 out of 5 by from A great solution Mass Building Code requires makeup air on Hoods greater than 400 cfm...I used the Broan damper with a pressure switch (you can purchase this combo) to operate the damper and it works fantastic. You simply place the pressure probe in your hood exhaust vent, the switch which is normally open, closes and completes the circuit to operate the damper. I will be using this on all my houses.

  • What is the noise rating on the motor for this damper

    A. The Broan MD8T does not have a sone or noise rating.
  • Will this work with any range hood?

    A. Yes, this will work with any 8" round ducting.
  • Will this work with the Broan model 336 1500 cfm exhust fan and how is it controlled?

    A. The Broan 336 requires a 10 inch duct and the Broan MD8T is for 8 inch ducts. This will only work if you get a duct increaser to your external exhaust fan. This unit is made to bring fresh air into your house. This only allows air to move in when your fan is operate.
  • If this will work with any range hood, what are the options for having it open automatically when the fan is activated?

    A. The Broan MD8T is wired directly to your range hood and the damper will open when the hood blower is turned on.
