Backdraft Damper prevents reverse air flow when fans are shut off. As a result, it saves CO2 and reduces the risk of odors flowing backward. It is made of galvanized steel. 

It also has exterior rubber gaskets pre-installed, which ensures an air-tight seal. It is a good investment for potential customers because of its high durability, easy-to-use technique, and cost-effective price.
