Circular attenuators are HVAC components designed to reduce noise transmission along ductwork while maintaining efficient airflow. Constructed from heavy‑gauge galvanised steel with internal acoustic lining (typically mineral wool or foam), they absorb and dissipate sound generated by fans and air movement. Ideal for commercial, industrial, and residential ventilation systems, circular attenuators help create quieter ducted environments without compromising performance.
Material:
• Heavy‑gauge galvanised steel outer casing
• Internal acoustic lining (e.g., mineral wool or polyester)
• Corrosion‑resistant and durable construction
Specifications:
• Type: Circular attenuator (noise‑dampening duct insert)
• Designed for round duct systems
• Available in a range of diameters and lengths
