Product Description
The GI Sound Attenuator (Duct Silencer) is designed to reduce noise generated by HVAC equipment such as air handling units (AHUs), fans, blowers, and ventilation systems while maintaining efficient airflow. It consists of a galvanized iron casing with internally mounted acoustic splitter pods filled with non-combustible sound-absorbing insulation protected by a perforated metal liner. The attenuator effectively minimizes regenerated and transmitted noise without significantly increasing pressure loss.
