Custom-made noise reduction for machinery
Industrial fans, blowers and compressors create large amounts of noise, which may not meet industry standards and could even cause permanent hearing damage to your employees. Industrial acoustic attenuators help reduce the noise emitted from this machinery, while allowing free air movement.
As with all Flexshield products, our acoustic attenuators are custom fabricated to suit your application. They are available in a wide range of materials and finishes. In most instances acoustic attenuators are pre-assembled, but can also be supplied as a flat pack, reducing the need for cranes or heavy lifting equipment.
Acoustic attenuators are made to withstand the rigours of the Australian environment. They are fabricated using materials ranging from galvanised or powder-coated steel to aluminium and stainless steel, allowing them to operate in extreme environments.
Accessories for our acoustic attenuators include:
- Mounting feet
- Weather hoods
- Support brackets
- Safety screens and bird mesh
- Lifting lugs
Acoustic attenuators are ideal for:
- Industrial centrifugal and axial fans
- Plant room air inlet and outlets
- Dust extraction systems
- Air compressors
- Exhaust plenum chambers
- Air conditioning plant rooms
- Cooling towers
- Generators and other machinery
They are also frequently used in conjunction with acoustic enclosures.
Acoustic circular attenuators
Cylindrical silencers are required where air flows through circular pipes. A standard silencer will allow the air to flow straight through, which results in an average noise reduction and a very low-pressure drop. A podded cylindrical silencer provides a more significant noise reduction, but may also increase the pressure drop.
Matching flanges and flexible joints are available to allow fixing to existing pipework.
Acoustic circular attenuators are ideal for:
- Boiler flues and vent pipes
- Dust extraction systems
- Vacuum pumps and blowers
