WITT Super Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks in accordance with EN 730-1 / ISO 5175. 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 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 70 °C / 158 °F

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
