They are not suitable for preventing a flame from within the pipe or system igniting the surrounding area (see MTP Deflagration Flame Arresters above).

The combination provides additional protection because the the flame
arrester element of the system is only actively required during
the short periods when the breather valve element of the system
is venting.

Suitable for pipe sizes from 2″ (50mm) up to 12” (300mm).

MTP flame arresters and breather valves are certified compliant with European ATEX and PED directives where applicable.
