Lightweight, low cost steel damper that enables users to select size, dimensions and material according to applications.

This is a butterfly damper type featuring a steel plate welded structure. It is used for ON-OFF and control of the flow of various gases and air. As there is no need for the wooden or metal molds normally used in the manufacturing process, a louver damper can also be fabricated.
