Ventilation silencer SP30

flow-controlpressure-controlvacuum

SP30 silencers are of the mixed type, progressive and controlled expansion of the fluid and absorption zone. The fluid passes through a diffuser made up of a series of perforated concentric elements with increasing passage section and then passes through an absorption zone. The diffuser is placed in a cylindrical body with walls covered with sound absorbing material protected with perforated sheet metal. DESCRIPTION SP silencers are built in a way that allows the free expansion of all the elements. These are devices that are open to the atmosphere, so there are no controls from official organizations or hydraulic tests. The silencer is a fixed point. For fluids with high temperature, an expansion device capable of absorbing the position variations of the pipes must be provided. Our silencers comply with the stipulations of Directive 97/23 / EC, since they are within the parameters set forth in article 3.3, according to report nº DEP.EPR.10.33156101 of the TÜV Rheinland Ibérica Inspection, Certification & Testing, S.A. Organism nº 1027. silenciadores para descarga a la atmosfera sp30 2 - Acoustic Silencer SP30 PROTECTION The exterior is protected by SA 2.5 blasting, inorganic zinc silicate and topcoat by high-temperature paint.
