Backdraft Dampers

Galvanized Back Draft Dampers feature a lightweight aluminum blade, which is spring loaded for positive closure. Prevents air from reverse flowing through the exhaust fan when it is powered off and helps keep cold air out!

Unique Features:
• Built for heavy duty installations
• Spring loaded for positive closure
• Requires minimal pressure to operate
• Perimeter gasket ensures the best seal
• Available in FIVE convenient sizes from 4″ to 12″

Grower’s Tip:
Use as another line of defense against odor control — will NOT allow contaminated air to escape from the area unfiltered.
