When noise radiating from downstream piping is a problem on reciprocating compressors, reactive or reactive-absorptive discharge compressor silencers will be necessary as well.įor centrifugal compressors, impellor blade passage frequency is usually the noise concern requiring treatment. If high mid-to-upper band noise is also a problem, then a reactive-absorptive compressor silencer should be used to address both concerns. Therefore, in most cases, it is essential to use a reactive inlet compressor silencer to dissipate the pulse energy.

Reciprocating compressors exhibited destructive low frequency pressure pulsations and noise.
