    • 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
    • Slave dampers 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
    • Slave dampers are designed to work with all BROAN® Automatic make-up air dampers including Direct Wire models MD6T, MD8T and MD10T, LinkLogic controlled models SMD6 and SMD8 and Universal models MD6TU, MD8TU and MD10TU

    Answer: 
    Contact Broan Technical Service @ 1-800-637-1453 as air pressure opens and closes the makeup damper. You can discuss the code requirements for your area and what is needed.

    Answer: 
    Thank you for your question on the model MD8S. The MD8S is an eight inch, motorized make up air damper. It does not have a fan in it and does not pull any air.

    Pressure Switch Not Working

    Greetings,

    I just installed an MD8TU in a ventilation hood system that's 900CFM...The sensor does not seem to be detecting the airflow and activating the damper...If you remove the hose and blow on it very slightly, it activates the damper motor, so for some reason, the pitot tube mounted on the duct is not picking up sufficient air to activate the pressure switch...
