Galvanized Steel Backdraft Damper for Ventilation Ducting
Built from durable galvanized steel, this backdraft damper is made for reliable performance in active ventilation setups. When your inline fan turns off, the internal flap closes to block reverse airflow, helping stabilize your environment and reduce backflow issues in duct runs.
Stop Reverse Airflow to Help Retain CO2 and Reduce Odors
By preventing air from flowing backward, it helps you save CO2 and limits odors from traveling the wrong direction through your ducting. A pre-installed rubber gasket on the exterior creates an airtight seal, improving efficiency and reducing leaks at connection points. Ideal for grow rooms, climate-controlled areas, and any ventilation system where backdraft control matters, it installs quickly and supports consistent airflow management.
