Rectangular louver damper

Rectangular louver damper consists of multiple blades installed parallel within a duct. It can control the flow of air and gases under both dry and wet conditions and can also provide isolation. In cement industry, it is commonly used at the inlet and outlet of equipment such as air preheaters and dust collectors.
