This small, compact flashback arrestor by the German company WITT has revolutionised safety in welding. The flashback arrestor provides protection against backfire, flashbacks and explosive mixtures in the gas supply. A multi-stage protection system, based on the dry flashback arrestor that WITT launched on the market around 75 years ago.
A modern quality flashback arrestor made by WITT has at least three protection elements: a gas non-return valve, a flame arrestor and a temperature-sensitive cut-off valve. A pressure-sensitive cut-off valve can also be added - ensuring maximum safety.
Flashback arrestors are available in brass or stainless steel, for all technical gases and all connections.

you should install one of these on your vaping electronic cigarette.
Butane isn't used for welding cutting and related processes because the flame is far too oxidising and temperature is far cooler than acetylene.
It doesn't need a flashback arrestor as the gas pressure / calorific value and flame temperature is far lower than propane acetylene propylene or Air Products Apachi gas.
Dear Mr. Perkins,
thanks for watching and you comment. Regarding butane you are right. This is not very common for welding and butane alone might not require a flashback arrestor. However, if oxygen or compressed air from cylinders or lines is also used, FBA are recommended. On the one hand, gas transfer, e.g. from the oxygen side, is to be prevented, on the other hand, however, gas or flame flashovers are also possible if a sudden combustion is caused by incorrect operation of the valves.

What is a check valve and is one need in addition to a flash back arrester?
A check valve is another name for a non-return valve. WITT has a wide range of non-return valves available. It stops the return gas flow, thereby preventing the formation of an explosive gas mixture. But it will stop a flashback only in specific cases and for special conditions regarding gas type and pressure. For this you require a Flashback Arrestor.
A high-quality flashback arrestor according to DIN EN ISO 5175-1 made by WITT does already include a gas non-return valve together with the flame arrestor and a temperature-sensitive cut-off valve.
It's always difficult to give you an advice without knowing your application. But in standard applications you normally do not require an additional check valve if you use one of these WITT FBAs according to DIN EN ISO 5175-1.

What type of pop sound come when we shut the torch..???
Thanks for your request. Not sure if I understand you correctly. The typical 'pop' sound can be described as a loud bang similar to a pistol shot.
Regards
Your WITT Team
@@WITTGAS yes but how that sound came when we shut the torch off..??
@@aliqadri4672Sorry, but in this case it is difficult to give advice. The sound could have many reasons. For example defective equipment. Please check if you close the supplies for flammable gas and oxygen in the right order.
Can these products be CE certified as per PED directive
Thank you very much for your question.
Our flashback arrestors DN20 (1") and bigger are CE-marked according to PED 2014/68/EU.

@@WITTGAS what about smaller size products?
According to the Pressure Equipment Directive, smaller flashback arrestors are not safety-relevant components related to pressure. They are manufactured according to good engineering practice and must not bear a CE mark.

Can it be used for the home for LPG
Hello. Thanks for your request.
In most cases WITT FBAs are used in industrial application. In general, many of our FBAs are suitable for LPG. Please note that our technical information regarding LPG is based on test with Propan.
Without having more detailed information we can't give you an advice whether one of our products is suitable for your application or not. We suggest to contact us via our website www.wittgas.com/contact.html. So one of our application specialists will be able to contact you and to answer your question.
Best regards,
Your WITT Team
There is no need to use a flashback arrestor on a domestic LPG installation at all because you are not using oxygen as part of it and it's totally unnecessary. It's only when you use Oxy / LPG processes that a flashback arrestor is necessary.
