Informatie

WITT RF Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks according to DIN EN ISO 5175-1, UL 1357/1358.

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 arrestor 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 dirtcontamination, extending the service life
a pressure relief valve RV 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 (Model RF53DN only)

Operation / Usage

RF Flashback Arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks
for pipeline outlets and single cylinders: Models RF53N, RF53DN and RF53NSK
for torches or burners with high flow: Model RF53NU
for cutting machines with high flow: Model RF53U
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 (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
