It is the combination of an intelligent microcomputer control system and a self-developed hydrogen and oxygen gas fire-retardant device. It adopts induction sensor plus intelligent microcomputer control system to cut off oxyhydrogen gas within 0.02 seconds.

The device is equipped with Okay Energy OH800-OH20000 oxyhydrogen generators,and added between hho machine and flame torches. For the process of welding and cutting,it not only protect the operator's safety,but also do not damage the oxyhydrogen machine's parts.

How does it work?
The hho machine’s gas pipe connects with the “gas in” of electronic flashback arrestor, and the hho gas flow out of ” gas out” connected with oxyhydrogen torch. When oxyhydrogen generator works well,the electronic flashback arrestor shows the red light.Once back-fire accurs, it automatically turn off the valve and shows the green light.

The new electronic flashback arrestor have unique advantages compared with the traditional wet type and dry type anti-backfire device:
1.Anti-backfire action within 0.02",no damage of hho machine parts
2.Continuous effectively anti-backfire protection
3.99.99% fire resistance rate
4.More safety and reliable performance
