SUCTION SILENCER

The suction silencer is used to reduce the suction noise of the compressor/ blower. It is constructed in circular shape. The fluid passes through the annular space of the acoustic packing where the sound energy is absorbed. The straight flow path through annular acoustic cylinder ensures minimum pressure drop

The following data are required to design suction silencer.

• Flow rate;
• Temperature;
• Inlet size;
• Allowable pressure drop and
• Silenced noise level requirements.
