Model 7A00
Detonation Flame
Arrestor
OBJECTIVE
The Model 7A00 detonation fl ame arrestor is a device that
can be fi tted to the opening of an enclosure or to the connecting pipe work of
a system of enclosures. Its primary function is to allow the fl ow of gases or
vapor of flammable liquids through the enclosure, but prevent the transmission
of a fl ame. The element inside the housing provides an extinguishing barrier
to the ignited vapor mixture by absorbing heat from the flame. The Model 7A00
is used as an independent safety system to ensure explosion protection.
TECHNIQUE
7A00 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.
