8" Backdraft Damper

Heavy gauge galvanized steel one-way airflow ducting. Prevents air leakage from your shop while system is not in use. Raw (uncrimped) on both ends. Not an explosion isolation device.

The Backdraft Damper will help prevent leakage of conditioned air into/out of your shop. Any draft that attempts to enter from your dust collector and back into the ductwork and/or your shop will be stopped by the one-way airflow gate within the damper.

Upon powering on your dust collector the system's high air velocity will lift the gate allowing air to flow into the system unimpeded. When you are done using your system gravity will automatically pull the gate closed.

Hand-crafted from galvanized steel the Backdraft Damper attaches at or near your system's inlet and has virtually no impact on your system's CFM.
