End-of-Line Flame Arresters

End-of-line deflagration arresters are designed to be installed at the end of a pipeline or exit vent from a vessel, where the ignition source is external, to provide protection against atmospheric deflagration.

End of Line Flame Arrester for use with Pressure/Vacuum Relief Valves

FE-IE series end-of-line deflagration arresters are designed to be used in conjunction with pressure/vacuum relief valves, to prevent propagation of flames in gas or vapour mixtures. FE-IE arresters are specifically designed to be located below the inlet of a pressure/vacuum relief valve, thereby providing an extra layer of tank protection.
