As breather/venting safety device incorporating an explosion and endurance burning flame arrester element for installation on top of storage tanks, tank access covers or breather lines. The breather allows the unimpeded flow of gases out to atmosphere and air into the tank/pipe thereby preventing vacuum locks whilst ensuring provision of a permanent and reliable protection against any flashback into the tank/pipe.

This device is not permitted to be installed in enclosed areas.

Approved for all materials of the explosion group IIA with a maximum experimental safe gap (MESG) > 0.9.

As breather/venting safety device incorporating an explosion and endurance burning flame arrester for installation on storage tanks containing particular categories of inflammable liquids providing for reliable and safe operation whilst ensuring protection against any possible flashback.

Approved for all materials of the explosion group IIA with a maximum experimental safe gap (MESG) > 0.9.

Fittings for screwing in armature housings, of endurance-burn proof pressure valves and combined PV valves for all inflammable liquids and vapours of explosion group IIA with MESG >0.9 mm and explosion group IIB1 with MESG ≥ 0.85 mm.

The condensate drain device enables draining of the condensate inside the housing to the outside and prevents flames from entering the valves.
