FLAME ARRESTER

A flame arrester comprising two part-bodies, which consist of different wire fabric layers and are connected to one another by an intermediate layer of particularly coarse-meshed wire fabric. The coarse-meshed wire fabric preferably consists of a thick wire. Both the wire diameter and the mesh width of this intermediate layer are preferably much greater than the mesh widths and wire diameters of the wires used for the part-bodies. The pressure relief body combines a high degree of mechanical stability with a great flame arresting capability and at the same time very low flow resistance.
