Designed and manufactured by Marsh Industries, the Whisspurr™ is an innovative AVR unit designed to reduce noise and vibration from diaphragm compressors.

Fitted inline between the compressor and air diffuser, the Whisspurr significantly reduces noise and vibration generated from the pulsation of the diaphragm compressor whilst enabling a consistent, unrestricted flow to the air diffuser.

The Whisspurr is predominantly used in the water and wastewater treatment sectors for sewage treatment plant aeration as well as fish husbandry, particularly Koi Carp ponds. However, the Whisspurr can be used with virtually any product which requires the use of diaphragm compressors.
