Circular Attenuator Mounting Flanges delivering quieter operation and upOur Circular Attenuators are engineered to deliver high performance noise reduction in ventilation and fan systems, available in bush, spigot and mixed connections. Designed for direct connection to metric axial flow fans and circular ductwork, they effectively reduce airborne noise while maintaining efficient airflow. The spigot option allows faster installation and removes the need for a flange ring, reducing installation time and overall cost.
