Description

SNVc CYLINDRICAL ACOUSTIC VENTILATION SILENCER FOR DUCT AND FANS UTILIZATION The NSVc range of silencers has been studied for ventilation installations. These silencers are intended to be installed in: • - Aspiration or impulsion of the helical fans. • - Suction or impulsion of centrifugal fans. • - Cylindrical ventilation circuits. The silencers admit an overpressure of 250 mm AC and a temperature of 100º C. Beyond these limits, please contact us. DESCRIPTION NSVc silencers are of the absorption type. There are two versions: Solution A: direct weight, provides without increased head loss, a sensible attenuation of the sound level. Solution B: has the same dimensions and is equipped with an aerodynamically soundproofing element, allowing a much greater acoustic efficiency to be obtained with a limited pressure drop. MANUFACTURING The NSVc to 900 silencers are made of galvanized sheet metal. The NSVc 1000 to 1600 silencers have the outer shell of black sheet metal with anti-rust paint and the inner parts of galvanized perforated sheet metal. The silencers are equipped with flanges. The absorbent material is rot-proof, non-hygroscopic and non-flammable fiberglass. DETERMINATION OF SILENCERS NSVc silencers are chosen based on the following criteria: • Acoustic efficiency (table I) and air flow noise (tables I and III). • Flow and allowable head loss (Table IV). • The dimensions (length and diameter) table V.
