Specifications
Silencers SMR are produced in absorptive design. They are intended for round ventilation systems ducts. Silencers reduce airborne noise transmitted by duct. Silencers are placed between noise source and protected room.Silencers up to diameter 315 mm are connected to duct by using of reduction fixed to the silencer body. Silencers with diameter more than 315 mm are connected to duct by using of clutch NSL.Silencer consist of the outer casing and inner perforated tube. This gap is filled by mineral wool with acoustic insulation properties. Insulation is coated by non woven fabric. Inner perforated tube is made of galvanized steel sheet.
