Fisher™ 6060 WhisperTube Modal Attenuator
Full-bore noise reduction solution 
  • Allows for up to a 10-15 dBA noise reduction inside pipe for any upstream source
  • Generates a negligible pressure drop and no impact on process flow
  • Patented design with internal acoustic cavities of varying sizes reduce noise across a broad range of frequencies
