The Ac Infinity Backdraft Damper Ducting Insert is a ventilation ducting tool designed for insertion into 6” ducting to prevent cold drafts and debris from flowing into ventilation systems. This product is made of sturdy galvanized steel and features two rings of outer rubber gaskets, which enable 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 Ac Infinity Backdraft Damper Ducting Insert is designed for heavy-duty performance in applications like overhead range hoods in kitchens and bathrooms. The spring-loaded antidraft damper 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 keeping pilot lights burning in water heaters, and keeping debris from entering inline duct fans in grow tents.
