The Model 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 vapor 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 vapor
mixture by absorbing heat from the flame. The Model
6E00 is used as an independent safety system to ensure explosion protection.
6E00 flame arrestors are designed on the principle of “quenching gap”. The crimped SST metal element allows
vapor 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.
Housing Material: Carbon Steel, Stainless Steel.
Trim Material: Stainless Steel (1.4571) element.
The Model 6E00 is designed, manufactured, and tested according to Directive 2014/34/EU (ATEX95) and ISO
The Model 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.
