Elmac Technologies - SV Series - Light Duty End of Line Flame Arresters - Data Sheet

SV SeriesFlame ArrestersLight Duty End of LineFlame Arresters withFixed ElementsTECHNICAL DATAPrinciple of OperationA flame arrester uses an element with small apertures whichallows gas or vapour to pass. If the apertures are smaller thanthe maximum experimental safe gap (MESG) for the gas orvapour then a flame cannot pass through the arrester,and is subsequently contained or extinguished.Benefits• Available in sizes from 15mm to 50mm nominal bore• Suitable for gases with MESG = 0.65mm (gas group IIB3)• Lightweight arresters in zinc alloy or aluminium alloy• Optional weatherhood for environmental protection• Male to female connection adapters available• The Elmac technical team can advise on specific location queriesGas GroupsElmac end of line deflagration arresters in the SV series are foruse with gases in Groups I, IIA, IIB1, IIB2 and IIB3.Standards ComplianceAll Elmac end of line deflagration arresters have been tested andcertified in accordance with national or international standards.Actual device performance is verified in the Elmac Technologies“state of the art” in-house test facility.Elmac ExpertiseElmac have been manufacturing flame arresters since 1948,and bring enhanced levels of flame and explosion protectionto a diverse range of applications.
