Back Draft Damper (Various Diameters)

These newly developed back-draft dampers are manufactured with quality components and precision engineering. The back-draft damper is used to prevent air from reverse flowing through the fan (when powered off) which allows no contaminated air to escape from the area untreated.

Can-Filters recommends the usage of back-draft dampers as another line of defense against odor control. CAN back-draft dampers are constructed from high quality materials and are used to allow vents to automatically shut when fans stop running.
