Principles of Operation

Elmac Technologies^® AVC Series 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.

A flame arrester uses an element with small apertures which allows gas or vapour to pass. If the apertures are smaller than the maximum experimental safe gap (MESG) for the gas or vapour then a flame cannot pass through the arrester and is subsequently contained or extinguished.

Explosion Groups

Elmac AVC Series End-of-Line Flame Arresters are ATEX certified for gas explosion groups IIB & IIC at a maximum operating temperature of +60°C. Suitable for Hydrogen Applications.
