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.
