Flash Back Arrestors


A flash back arrestor is a safety device that shuts off gas flow in event of combustion of a flame mixture that can occur within your gas management system. This can travel back through the line of your gas management system to you gas source if a flash back arrestors is not in line.

A flash back arrestor shuts off gas flow and extinguishes the flame before it can reach your gas source. Several factors can cause flash back, including failing to purge line properly, using improper pressure, leaks in your gas management system and improper system operation. We recommend using a flash back
arrestor on your fuel line, Acetylene Plants as well as the oxygen line.

Wet Type Flash Back Arrestor

(Model :FBA-WT)


A flash back arrestor is a safety device that shuts off gas flow in event of flash back. Flashback is the
combustion of a flame mixture that can occur within your gas management system. This can travel back through the line of your gas management system to you gas source if a flash back arrestors is not in line.

A flash back arrestor shuts off gas flow and extinguishes the flame before it can reach your gas source. Several factors can cause flash back, including failing to purge line properly, using improper pressure, leaks in your gas management system and improper system operation.

We recommend using a flash back arrestor on your fuel line as well as the oxygen line. The Flash Back Arrestors are made to international standards and confirm to BIS: 11006 These Flash Back arrestors are a qualitative product.

The water and the disk works like a flame arrestors and quenches the flash back and the Non return valves at the bottom of the FBA cuts off flame in the event of any flash back in the down stream equipment. Further relief valve provided at the top releases vapor and hot gases and prevent damage to the equipment.
