The Grilletech Round Butterfly Backdraft Damper is a smart HVAC solution designed to regulate airflow efficiently and prevent reverse drafts. Ideal for both residential and commercial systems, it automatically opens during airflow and closes when idle, minimizing energy loss and enhancing indoor air quality by blocking pollutants and reducing condensation. Its easy installation, directly onto the exhaust fan’s circular mouth, eliminates the need for extra ductwork, saving time and cost. Proper sizing, professional installation, and regular maintenance ensure maximum performance and system efficiency.
