Many high speed multi-plunger compressors create tones and pulses which can be both harmful to the piping system whilst at the same time seeming to propagate through both piping and vessels to radiate noise that becomes and annoyance to nearby workers and residences.

Typical applications include multi-plunger compressors, vanes compressors and refrigeration compressors.

With the Flo-Dyne acoustic filter, it is possible to completely eliminate these tones and pulses by the application of our simple low pass acoustic filter design.

Using a multiple chamber design with connecting choke tubes, we are able to provide proven acoustic attenuation that will virtually eliminate tones and pulses from high speed positive displacement compressors.
