Application
Elmac Technologies® MB-IB series of microbore flame arresters is specifically designed for the protection of gas sampling and analysis equipment where flammable vapours are present. Many other applications involving small bore pipework can be protected from explosion risk using microbore arresters.

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.
