Both suction and discharge silencers shall be supplied either in circular or rectangular construction for fan/ blower and turbo blowers. The rectangular silencer shall be of absorptive type installed either at suction side or at discharge side of fan/ blower. The internals of the silencer comprises a series of acoustic splitter elements arranged in parallel inside the rectangular steel casing. This would ensure the flow of air/gases through the rectangular air gap between acoustics splitters and thus offering a minimum pressure drop. The leading and trailing edge of the acoustic splitters will be designed aerodynamically to offer minimum resistance to the flow medium.
