CC Series Circular Attenuators

  • The Q-Tech high performance CC Series circular attenuators are a popular solution for reducing the noise of smaller HVAC systems utilising round duct.
  • Units are lightweight, spun end caps are designed for easy connection to a fan or ductwork. Connecting ductwork can be rigid or flexible, matching spigot sizes.
  • CC attenuators are ideal in situations where more acoustic performance is required than what can be obtained with a suitable length of acoustic flexible duct and cost precludes the use of lined metal duct.
  • Where breakout noise is a critical design parameter, refer to the Rectangular and Circular Series Attenuators.
