Designed specifically for use with in-line fans, the RSK Series Dampers feature a galvanized steel tube and aluminum flaps. The flaps are spring-loaded and close to provide a seal when the fan is switched off. They can also be used as simple backdraft dampers in a duct system. The pressure loss through these units must be added to the system loss before selecting the fan.
