Safety Devices (Flashback Arrestor) - World Class Safety Equipment

YOUR SAFETY IS CLOSE TO OUR HEARTS

A safety device is absolutely necessary at every gas take-up point. Messer Cutting Systems offers you a comprehensive program to DIN EN 730-1, DIN EN 561, as well as to ISO 5175 and ISO 7289. Regardless of whether they are for a cylinder pressure regulator, as outlet for a gas supply panel or directly on a hand or machine torch, the safety devices from Messer ensure your safety. The combination of gas shut-off valve (NV), flame arrestor (FA) and thermal gas cut-off system (TV) offer you the optimum protection against flash-backs and gas reverse flow.

We would be happy to consult with you to decide together which safety units are ideal for you.
