Round Backdraft Dampers

Round backdraft dampers are devices used to prevent the backflow of air in ventilation systems. They are typically installed in the ductwork of commercial and industrial buildings and are designed to allow airflow in one direction while preventing airflow in the opposite direction. Round backdraft dampers work by using a spring-loaded or gravity-operated door that closes when air flow in the opposite direction exceeds a certain level. When the airflow is in the correct direction, the door opens, allowing air to flow through the ductwork.
