Product Description

A ventilation ducting tool designed for insertion into 8” ducting to prevent cold drafts and debris from flowing into ventilation systems. Built to be embedded in ducts, the backdraft damper is made of sturdy galvanized steel and features two rings of outer rubber gaskets. This enables it to grip your ducting with an airtight seal in either a horizontal or vertical orientation. The butterfly damper blades are made of aluminum and are equipped with a light spring that folds with minimal airflow.

Applications

The spring-loaded antidraft damper is built for heavy-duty performance in applications like overhead range hoods in kitchens, bathroom fans and tumble dryers. It can be fully or partially inserted into your duct work using the rubber rings to hold itself in place. Other one-way airflow uses include keep pilot lights burning in water heaters and keeping debris from entering inline duct fans in grow tents.
