DL Wholesale Backdraft Damper - 10-in

Stop Reverse Airflow When Fans Shut Off - 10-in Duct Fit

When an exhaust or inline fan stops, air can drift back through the ducting and carry outside air and odors into your growing space. This backdraft damper closes against reverse flow, so air moves in one direction only. It is made of galvanized steel and has a rubber gasket pre-installed on the exterior to help seal against the duct.

This 10-in unit suits growers running 10-in ducting in a tent, room or dedicated cultivation space who want to keep conditioned air and odor control working when fans cycle off. It is sold individually, so you can fit one per duct run as needed.

Key Features & Benefits

• Backdraft prevention — blocks reverse airflow when the fan is off.
• Galvanized steel body — gives a rigid, durable housing for ducting.
• Pre-installed rubber gasket — supports a tighter seal on the exterior.
• Odor and CO2 retention — helps keep odors from flowing backward and helps retain supplemental CO2 in the space.

Who Should Use DL Wholesale Backdraft Damper

Indoor growers, from home gardeners to licensed commercial operations, who use 10-in ducting with exhaust or inline fans and want to limit reverse airflow during vegetative growth and flowering.
