Control noise while still providing the required airflow

Acoustic attenuators are ideal when you need to control noise and still provide the required airflow for your application. AcousTech will select, design and manufacture soundproof attenuators to suit your individual situation.

Soundproof 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
  • Positive displacement blowers
  • Diesel engine driven generators and other machinery
  • Frequently used in conjunction with acoustic enclosures
  • And many more applications.

AcousTech attenuators are packed with special features

We fabricate acoustic attenuators or acoustic splitters in a wide range of materials and finishes. AcousTech manufactures a unique kit-form acoustic splitter attenuator that is perfectly suited for rooftop or basement plant rooms and gen sets.

Supplied in a flat pack format, the acoustic attenuator is easily taken to the installation site without the need of cranes or heavy lifting equipment.

Circular attenuators

Generally required where a gas or air flows through circular pipes, circular attenuators will allow the gas to flow straight through, resulting in an average noise reduction and very low pressure drop. The addition of a pod into the attenuator provides a greater noise reduction, but may also increase the pressure drop. Matching flanges are provided to allow easy fitting to existing pipe work.

Circular attenuator applications

  • Industrial centrifugal and axial fans
  • Boiler flues
  • Dust extraction systems
  • Screw axial and reciprocating air compressors
  • Vacuum pumps
  • Positive displacement blowers

Available in all sizes for all applications

Acoustic attenuators are custom fabricated to suit any opening size, acoustic or airflow requirements. Once you choose a desired size, AcousTech will supply your easy-to-install soundproof louvres quickly.
