Exhaust silencer SRA

ventilationfor blowersfor pumps

SR silencers are designed to efficiently reduce suction and exhaust noises of Roots type blowers, vacuum pumps and water ring or vane type rotary compressors. These silencers have been perfected in the laboratory by means of analogical research. RANGE Four types of compressor and pump SR Silencer are available, classified in three categories below: • SRa type silencer for suction and exhaust of air or dry gases. • SRv and SRd type silencers for exhaust of air or dry gases. • SRdS type silencers or separator silencers of vacuum pumps with air or gas loaded with liquid particles. This is the case of water ring vacuum pumps or water injection Roots type blowers. The nominal diameter of inlet and outlet piping defines the denomination of the silencers. CONSTRUCTION SR silencers are entirely constructed in welded steel. A coat of zinc chromate rustproof paint has been applied to the exterior surfaces of these silencers and the interior is protected by a coat of aluminium paint. Maximum admissible pressure is 1 effective bar. OPTIONAL EXTRAS • Flanges and counter flanges. • Sets of gaskets and bolts. • Supports for vertical position (gussets) or horizontal position (frames) • Drains (always provided on SRdS silencers). • Construction in special steels. • Exterior protection by zinc metallization Please get in touch with our company for diameters above 450 mm.
