SIS Absorptive Silencer

    SIS absorptive silencers are designed and developed to reduce noise generated during suction and/or discharge of Sicflux fans and exhausters. Made of galvanized steel 1020 and internally coated with sound-absorbing material, these silencers feature flanged connections with holes for easy installation.

    Available in two diameters and with two length options, they can be adapted to meet various sound attenuation needs. They are also compatible with the ACI and CRS lines.
