Information

WITT RF Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks in accordance with DIN EN ISO 5175-1. 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
  • 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 vents excessive pressure and soot into the atmosphere, protecting the hose from bursting and the flame arrestor from clogging up, thus maintaining the flow rate
