Can-Filters Backdraft Damper


Can-Filter Backdraft Dampers are manufactured with quality components and precision engineering. The backdraft damper is used to prevent air from reverse-flowing through the fan (when powered off), which allows no air to flow through untreated. Can-Filter recommends the usage of backdraft dampers as another line of defense against odor control.

Backdraft Dampers are available in 5 sizes from 4″-12″



  • Available in sizes from 4″-12″
  • Spring-loaded for positive closure
  • Rigid design is constructed from galvanized steel for the collar and lightweight aluminum for the damper blades
  • Can be mounted horizontally or vertically for horizontal or vertical airflow
