The FAMCO Butterfly Damper (BD) is used as a backdraft damper for heat exchangers, exhaust systems, solar heating systems and other intake or exhaust applications where a powered damper is not needed. This damper works in both horizontal or vertical positions and the foam seal provides minimal air leakage. Due to its unique design it opens easily with normal airflow and closes with gravity. FAMCO’s backdraft dampers are quality constructed in galvanized steel metal, built to last, and come at a relatively affordable price. Without a quality backdraft damper, the overall circulation of air in your home will suffer.

Why is a backdraft damper important?

There are a few reasons why this one piece is especially critical. A backdraft damper, while small, plays an important role in supporting the overall function of your entire ventilation system. Without it, your air quality will suffer, and odors caused by bacteria are more likely to persist, especially in hot and humid rooms. Simply put, a backdraft damper allows for contaminated air to be transferred out of the room and prevents reverse airflow.
