Broan-NuTone Range hood Damper

NuTone® 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 (MD6S, MD8S, and 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.
