Description
Backdraft dampers (also called gravity dampers) are used in exhaust and intake HVAC systems to allow airflow in one direction while preventing reverse flow. They rely on gravity to close the damper when the air pressure changes, have a mechanical butterfly design, and male and female ends. These round, steel backdraft dampers are available in 6, 8, 10, and 12-inch models.
They can be used any HVAC appliance where air direction control is needed.
