The Fantech RSK8 Backdraft Damper is a 8" duct damper with a galvanized steel collar and aluminum damper blades. RSK models are a spring loaded design that creates positive pressure that prevents airflow.

The spring loaded design creates positive pressure closure preventing airflow through the damper when the system is shutdown.

Backdraft Prevention
By incorporating spring-loaded blades, backdraft dampers ensure that airflow only moves in one direction, effectively preventing the backflow of air into the system.
