The Marsh Whisspurr Acoustic Vibration Reaction (AVR) unit has been designed to limit noise levels and vibrations from diaphragm compressors used in the water and wastewater treatment sectors.
Suitable for all types of compressor including; Bibus Secoh, Nitto and Charles Austen, the Marsh Whisspurr AVR unit is easily fitted inline between the compressor and air diffuser. If space permits, the Marsh Whisspurr unit should be fitted as close as possible to the compressor – preferably, inside the sewage treatment plant.
Please note, the Marsh Whisspurr Acoustic Vibration Reduction unit is chemically sealed and bolted shut, which 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. This unit is also not suitable for side channel blowers.
The Marsh Whisspurr Acoustic Vibration Reduction unit’s innovative design ensures that any noise pollution emanating from the compressor unit is dramatically reduced without hindering the overall performance of the treatment system. Rural areas, where continuous noise is a nuisance, particularly benefits from AVR unit’s noise and vibration reduction qualities.
Available in four standard sizes, the corrosion free Marsh Whisspurr AVR unit does not require any electrics and can be easily installed into existing wastewater and water treatment systems.

Question:
does the avr come already fitted if brought with the treatment plant
Answer:
The Marsh Whisspurr W-AVR Acoustic Vibration Reduction Unit is not typically pre-fitted to the treatment plant when purchased. It is designed to be easily installed inline between the compressor and air diffuser of your existing or newly purchased system. If space permits, it should be fitted as close as possible to the compressor, preferably inside the sewage treatment plant. You can find detailed installation instructions in our Installation Guide. Please note, any tampering, breaking of the seal, or removal of any bolts on the unit will invalidate the warranty and may prevent the unit from working effectively. If you wish to have the unit pre-fitted before delivery, I recommend contacting our customer service team to discuss this possibility.
