    Information

    WITT Super Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks in accordance with DIN EN 5175-1/DIN EN 5175-2. Every Arrestor 100% tested.

    The best Flashback Arrestors in the world

    • a large surface area flame arrestor FA of stainless steel construction extinguishes any dangerous flashback entering the device in any direction
    • after any flashback or reverse gas flow, a pressure-sensitive cut-off valve PV immediately cuts off the gas supply and prevents dangerous further work
    • a red signal lever indicates the operation of the pressure-sensitive cut-off valve
    • the resetting of the arrestor via the lever allows the user to resume safe work immediately after fixing the cause of the flashback or the reverse gas flow
    • a temperature-sensitive cut-off valve TV extinguishes sustained flashbacks long before the internal temperature of the arrestors reaches a dangerous level
    • a spring-loaded check valve NV prevents slow or sudden reverse gas flow from forming explosive mixtures in the gas supply
    • a filter at the gas inlet protects the arrestor against dirt contamination, extending the service life
    • a pressure relief valve RV vents excess pressure and soot into the atmosphere, protecting the hose from bursting and the flame arrestor from clogging up, thus maintaining the flow rate

    Operation / Usage:

    • Super Flashback Arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks
