Whisspurr

Product Description

Whisspurr™ – Acoustic Vibration Reduction (AVR) unit

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.

WRc Test Conclusion

The Water Research Centre came to the following conclusion when testing the Whisspurr unit in October 2021.

The pressure drop observed for both Whisspurr AVR units is very small 0.03 Bar or less for all pumps and flow conditions. With such a small pressure drop any impact on the pump and or air diffuser efficiency will be insignificant and not observable without detailed scientific measurement.

The use of the AVR 1 and 2 units results in a significant drop in the sound level, and the distance the sound travels from the source. In addition to the scientific sound measuring equipment this reduction was very clear to the persons undertaking the testing.
