Backdraft Dampers
Backdraft dampers, also called gravity dampers, keep air flowing in one direction through an HVAC duct. These dampers open when the ventilation system is running and close dynamically to prevent the backflow of air or materials.
Round Backdraft Dampers
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.
