SOLER & PALAU BD8 8" Back Draft Damper

The SOLER & PALAU BD8 Back Draft Damper operates through gravity-controlled blade movement to manage airflow and prevent unwanted air return in ventilation systems. It is typically installed in exhaust or intake duct runs where it remains open under normal airflow conditions and closes automatically when airflow stops or reverses. The 8-inch size refers to the duct connection diameter for integration into compatible round ducting. Commonly applied in HVAC systems, it is positioned within ventilation pathways such as exhaust lines and air distribution runs.
