A Compressor Discharge Silencer can be rectangular or cylindrical in construction. The circular silencer is made of concentric annular acoustic cylinder enclosed in a robust steel casing with transition cone or dished end at both ends with inlet and outlet nozzles. The silencer casing with inlet and outlet nozzle will be designed as pressure vessel.The air/ gas enters the silencer and passes through the annular space between the concentric annular acoustic cylinders where the sound energy is absorbed. The straight flow path through annular acoustic cylinder ensures minimum pressure drop. Either steel, galvanized steel or stainless steel is provided for internals based on the customer’s choice.
