SOLER & PALAU BD10 10" Indoor Round Backdraft Damper TRC500

The SOLER & PALAU BD10 Indoor Round Backdraft Damper TRC500 prevents reverse airflow in ducted ventilation systems. It operates through a gravity or spring-assisted blade mechanism that opens, when air is pushed through the duct and closes when airflow stops, blocking unwanted backflow. This maintains directional air movement through exhaust or supply lines. It is installed in round 10-inch duct sections connected to exhaust fans, inline blowers or ventilation terminal within HVAC systems. The damper supports controlled air movement in residential and commercial ventilation setups, maintaining proper airflow balance across duct networks during system operation.
