Flashback Arrestor Super 66

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 by 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 non-return 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
