Silencers are system that allows the passage of airflow whil  simultaneously facilitating reduction to the passage of sound (or noise) in “air moving” applications such as air conditioning or ventilation system, dust control equipment, motor cooling fans. Cylindrical attenuators are designed mainly for use with axial flow fans however they can also be adapted for ducted applications.
The attenuators are insulated by acoustic infill and, for Cb series, a central-pod is placed in the silencer for higher attenuation.
