Application
The Elmac Technologies® SVE series of light duty end-of-line deflagration arresters is designed for installation at the end of a pipeline or on an atmospheric vent from vessels where flammable gases or vapours may be present. SVE arresters provide an economical solution for situations where a simple light weight product is required. Typical applications include gas purging of equipment, sample lines and instrumentation lines.

Principle of Operation
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.
