The silencer is mounted on a duct section with the purpose of reducing the noise generated by the airflow and/or caused by the fan’s vibration.
The casing is made of galvanized steel. Sound-absorbing panels are installed on the inside faces, (panel width “p” is 100 or 200 mm, depending on the noise reduction requirement and on the pressure drop).
Supplied with flanged ends.
