6A00 Deflagration Flame Arrestor

The 6A00 inline deflagration flame arrestor is a device that can be fitted to the opening of an enclosure or to the connecting pipe work of a system of enclosures.

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.

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

The 6A00 is used as an independent safety system to ensure explosion protection.

The 6A00 flame arrestors are designed on the principle of “quenching gap”.

The crimped SST metal element allows vapour to pass through in order to allow a vessel to breath, yet prevents the propagation of a flame from the exposed side to the protected side.

The 6A00 is designed, manufactured, and tested according to Directive 2014/34/EU (ATEX95) and ISO 16852. The single element design is bidirectional and
available for horizontal or vertical installations.

The maximum distance between flame arrestor and ignition source should not be more than 50 x the diameter of the connection size for most hydrocarbon gases.
