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 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

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
WITT Flashback Arrestors may be mounted in any position /orientation
only one piece of equipment may be connected to a single Flashback Arrestor
the maximum ambient / working temperature is 60 °C / 140 °F
gases: acetylene, town gas, natural gas, LPG, hydrogen, oxygen, compressed air, ethylene (more upon request)

Maintenance:

annual testing of the non-return valve, body leak tightness and flow capacity is recommended
WITT is happy to supply special test equipment
Flashback Arrestors are only to be serviced by the manufacturer; the dirt filter may be replaced by competent staff
