Backdraft Dampers

Backdraft Dampers

Release hot exhaust from your heating system without allowing cold air inside with these backdraft dampers. They have spring-assisted blades that open easily to allow airflow in only one direction. Often used in areas where hot air accumulates, such as in furnace rooms, attics, and chimneys, these dampers are great for use with belt-driven centrifugal roof and wall ventilators. Not for use in kitchen exhaust applications.

For Walls

Use these dampers with wall-mount ventilators.
