The Fantech RSK6 is a six inch duct backdraft damper designed for ventilation systems. This damper features a galvanized steel collar and aluminum damper blades. It uses a spring-loaded mechanism to maintain positive pressure, preventing unwanted airflow when the ventilation system is turned off.
This backdraft damper is suitable for residential and commercial ventilation applications. It effectively prevents backdraft during system shutdown, ensuring air does not escape through the duct.
