Multi-Function Gas Safety Device
The SIMAX 5 is a high-capacity multi-function flashback arrestor engineered for the protection of tapping points, distribution lines, and gas manifold systems. Manufactured in Germany and compliant with DIN EN ISO 5175-1 and AS 4603, it delivers comprehensive safety performance for industrial gas installations requiring high flow and robust protection.
Designed for central gas supply and manifold applications, the SIMAX 5 integrates multiple safety elements into a single, serviceable unit, providing reliable protection against flashback, backflow, overheating, and contamination.
Integrated Safety Functions
Gas non-return valve (NV): prevents reverse gas flow and dangerous gas mixtures
Flame arrestor (FA): stops flashback propagation
Temperature-sensitive cut-off valve (TV): shuts off gas flow if excessive temperature is detected
Dust filter (DF): protects internal safety components
100% factory tested for safety and performance
