Dampers are normally installed in the stacks or ducts of power plants or other variety fields for intercepting media. With the function of fully open and close, this equipment could make the system media at the pipeline fully circulated or cutoff.

 

Dampers could be in the shape of square or round which are based on the ductwork that dampers will be installed with, and could be classified as manual operating damper, electric damper and pneumatic damper by the driven mode.

 

Dampers are mainly made from several components as frame, blade, seals, shafts, bearings linkages and actuation.
