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 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. A one-way airflow duct tool designed to prevent exhausted air and odors from sweeping back into ventilation systems. In any air delivery system, residual air that lingers can drift back into the area you want to keep clean. This wastes the efforts of your high-powered fan, forcing you to run it longer and increase your energy use. The backdraft damper is everything you need to ensure air and odor flows in one direction and keep your space well ventilated. The lightweight shutter blades are made of aluminum and easily open to airflow. Spring-loaded to close when your fan is turned off. Once the butterly blade dampers are closed shut, they block exhausted air and odor from flowing the other way, ensuring full ventilation. Outer rubber gaskets line the backdraft damper to provide grip on your inner duct lining. Allows you to install it in horizontal or vertical orientations. A sleek body that is crafted with galvanized steel and finished with black powder-coated paint. Offers a strong build with aesthetic looks.
