Introducing Whisspurr, the innovative AVR unit designed to reduce noise and vibration from diaphragm compressors used in the water and wastewater treatment sectors.
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 unit is suitable for all types of compressor; Bibus Secoh, Charles Austen, Nitto, etc.

> The Whisspurr AVR unit is chemically sealed and bolted shut. This creates a pressure vacuum when in operation. Any tampering, breaking of the seal, or removal of any bolts will invalidate the warranty and will prevent the unit from working effectively.
