To prevent smoke or harmful gases that have already been exhausted from flowing back in the event of a fire or when the fan suddenly stops for various reasons—because when the fan stops, it enters a high-pressure state while the system remains at low pressure—the device serves to block reverse airflow. Depending on the installation method, it can be installed horizontally or vertically.
