Wall-mount backdraft dampers, also called wall shutters, install vertically onto the wall vents of an HVAC system and prevent air from flowing backward. They feature spring-loaded blades that open when the system is running and close when it is not to keep the conditioned air in the occupied space.

Ceiling- and roof-mount dampers install horizontally onto openings in the ceiling or roof and help prevent backflow. They feature spring-loaded blades that open when the HVAC system is running and close when it is not to prevent conditioned air from flowing backward and leaving the occupied space.

Universal-mount dampers install onto vertical or horizontal vents and ensure that air flows in the correct direction. They feature spring-loaded blades that open when the system is running and close when it is not to keep the conditioned air in the occupied space.

Round dampers install into round duct branches and ensure that the air flows in the desired direction. They can be mounted either vertically or horizontally.

Motorized wall-mount backdraft dampers, also called wall shutters, install vertically onto the wall vents of an HVAC system and prevent air from flowing backward. They feature integrated motors that open when the system is running and close when it is not to prevent the backflow of air or materials.
