ONNLINE SILENCER ROUND PVD 400-900-50 ONNLINE

Online silencers are used in round duct systems to reduce the noise from air handling units and to minimize sound transmission through ductwork from one space to another.

The silencer has been tested in accordance with the ISO 7235 standard and meets class C airtightness requirements. Online silencers are suitable for a variety of applications, including renovations, retrofits, and confined spaces. The silencer is manufactured from high-quality hot-dip galvanized steel sheet. The outer flange is longitudinally welded. The sound absorption material is an Acutec element (polyester) covered with fiber fabric or perforated sheet. The total thickness of the absorption material is 50 mm. The silencers can be connected to the duct using rubber gaskets. The product is equipped with duct connections compliant with standard SFS 3282. The silencers can be cleaned using a rotating nylon brush, by vacuuming, or by wiping with a damp cloth. Features
