Circular duct silencer

Round galvanized duct silencers for installation in between ducts. The casing is made from a spiral duct outer layer and perforated sheet steel as inner wall. 50 mm mineral wool is used for sound insulation. The polyester fabric between the perforated inner wall and the mineral wool prevents wool from penetrating into the duct. If a higher noise attenuation is needed, multiple silencers can be mounted successively.
