The spacer is a component that is generally used in a PROTEGO® flame arrester as a spacer within the FLAMEFILTER® set.
It is intended to prevent FLAMEFILTER® FLAMEFILTER® A FLAMEFILTER® is a circular disk, which is made by coiling serrated and plain metal band alternately. s from lying directly on top of each other and thus covering each other's gaps. Spacers also serve as a stabilizer when the pressure wave hits the FLAMEFILTER® during detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). / deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). . Spacers come in various shapes and are made of different wires, wire meshes and wire cloths. In addition to their function as stabilizers and spacers, certain types of spacers also serve to improve flame transmission resistance.
