6E00 Flame Arrestor

The 6E00 end-of-line deflagration flame arrestor is a device that can be fitted directly on a vessel, tank vent nozzle, or on the end of a vent line.

Its primary function is to allow the flow of gases or vapour of flammable liquids through the enclosure, but prevent the transmission of a flame from the outside.

The element inside the housing provides an extinguishing barrier to the ignited vapour mixture by absorbing heat from the flame.

The 6E00 is used as an independent safety system to ensure explosion protection.


The 6E00 deflagration flame arrestor is a passive device with no moving parts. The flame cell element can be easily removed for inspection and cleaning in appropiate solvent solution.


Units are available in DN20, 25, 32, 40, 50, 80, 100, 150, 200, 250, 300 (3/4″, 1″, 1-1/4″, 1-1/2″, 2″, 3″, 4″, 6″, 8″, 10″, 12″) line sizes; thread connections according to ISO7/1, BS21 or ASME B1.20.1.

Standard for flange connections to EN1092-1 PN10, ASME B16.5 150#RF or JIS B 2220 10K.


The 6E00 is designed, manufactured, and tested according to Directive 2014/34/EU (ATEX95) and ISO 16852.
