Backdraft Shutters
Backdraft shutters (or Butterfly Dampers) are commonly used with inline exhaust fan systems. They are a necessary component for installation in 6 star rated energy saving homes. We sell backdraft shutters in both plastic and metal, with a variety of sizes available depending on the size of fan and ducting you are using. We even stock backdraft shutters for non-ductable fans.
A backdraft shutter is a draft stopper designed to prevent air flowing in the wrong direction when the exhaust system isn’t in operation. The shutters open with the pressure generated by air stream then closes automatically.
