AC Infinity | Backdraft Damper Ducting 6" Galvanized Steel

A one-way damper that slides inside 6" ducting to stop air, cold drafts and debris from coming back through the line. The aluminum butterfly blades are on a light spring and open with very little airflow.

Two rubber gasket rings grip the duct for an airtight fit, and it can be fully or partly inserted, horizontally or vertically. The steel body is 5.03 in long with a black powder-coat finish. In a grow tent, it keeps debris out of the inline fan; it also works on range hoods, bath fans and dryers.

Pairs with: AC Infinity CLOUDLINE S6 inline fan, Active Air Premium Ducting 6" x 25', Grow1 Stainless Steel Duct Clamp 6in.
