MB-IB Def. SeriesFlame ArrestersMicrobore In-LineDeflagration ArrestersTECHNICAL 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 15mm and 20mm nominal bore• Suitable for gases with MESG = 0.65mm (gas group IIB3)• Available in carbon steel or stainless steel• The Elmac technical team can adviseon specific location queriesGas GroupsElmac in-line deflagration arresters in the MB-IB series are for usewith gases in Groups I, IIA, IIB1, IIB2 and IIB3.Standards ComplianceAll Elmac in-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.
