Frequently asked questions about flashback arrestors:
A flashback is an ignition of mixed gases in an oxy-fuel cutting and welding system.
Are flashback arrestors and check valves the same?
No. A check valve stops the reverse flow of gas; a flashback arrestor is designed to help stop the advancement of a flashback fire. Smith s flashback arrestor with built-in check valve does both.
Why do I need a flashback arrestor?
Mixed gas explosions and flashback fires can result in damage to equipment and/or severe personal injury or death. Smith flashback arrestors with built-in check valves help prevent accidents caused by the reverse flow of gases and flashback fires.
What is the minimum pressure required to allow gas to flow through the flashback arrestors?
The built-in check valve requires a minimum of 2 psi to open allowing gas to flow through.
