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 temperatureof the arrestors reaches a dangerous level
• a spring loaded non-return valve NV prevents slow or sudden reverse gas flow forming explosive mixtures in thegas supply
• a filter at the gas inlet protects the arrestor against dirtcontamination, extending the service life
• a pressure relief valve vents excessive pressure and sootto the atmosphere protecting the hose from bursting andthe flame arrestor from clogging up thus maintaining theflow rate (only RF53DN)
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, RF53DNand RF53NSK
• for torches of 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 singleFlashback Arrestor
• the maximum ambient / working temperature is 70 °C
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 manu-facturer. The dirt filter may be replaced by competent staff
ApprovalsCompany certified according to ISO 9001:2000 and ISO 14001
WITT RF Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks according to EN 730 / ISO 5175-1 Certified and under surveillance

TestsEvery WITT Arrestor is tested individually for body leaks, non-return valvefunktion and is subjected to flashback testing at the maximum rated operating pressure in accordance with ISO standards or those of thecountry of sale.
MaintenanceNo maintenance is required. Nevertheless it is recommended that at annual intervals the units are tested with clean dry air or nitrogen for body leakage and against reverse flow. Test specifications and test equipment available on request.
InstallationThe WITT Automatic Flashback Arrestor may be installed at regulator orpipeline outlets. For pipeline use a shut-off valve should be fitted immediately upstream of the arrestor. If there is a danger from water vapour being carried with the gas, then a seperator should be installedupstream. Not more than one process unit may be connected to oneflashback arrestor. It may be mounted horizontally, vertically or any other position. The maximum working temperature is 70° C.
RepairsDetective units as well as units with temperature activated cut-off valve closed should only be serviced by the manufacture or his authorised local representative as it requires full testing including flashback testing after reassembly. The change of the dirt filter is notpart of this requirement and can easily be carried out.

Description:
The WITT Automatic Flashback Arrestors RF 53 N,85-10 and 85-30 incorporate:
• Large surface mesh filter to remove dirt particles from the gas to improve service life ofthe arrestor.
• Spring loaded non-return valve to prevent slowor sudden backfeeding. It is protected fromflashbacks by the downstream arrestor element.
• Large surface area flame arrestor of sintered stainless steel to extinguish any flashback entering the device in any direction. The cylindrical shape gives high flow capacity.
• Temperature activated valve to cut-off the gassupply before the internal temperature reaches a dangerous level. The sealing element is shrouded from flashbacks and the valve closesin the same direction as the gas flow ensuringthat it cannot be re-opened by the gas inletpressure.
WITT Automatic Flashback Arrestors RF 53 N, 85-10 and 85-30 conform to EN 730-1, ISO 5175and other national standards.

Benefits
• extinguish dangerous flashbacks with sintered stainless steel elements FA
• immediately cut off the gas supply, and therefore prevent dangerous further work after any flashback or gas backflow via pressure sensitive cut-off valve PV
• extinguish sustained backfire – via temperature sensitive cut-off valve TV
• avoid the formation of explosive mixtures in the gassupply – via non-return valves NV
• indicate flashbacks and gas backflow optically – via red alarm mark
• allow simple resumption of work after the cause ofhazard has been removed – via resetting the sleeve
• offer long service life due to protection against dirt – via filter at gas inlet
Operation / Usage
• the Flashback Arrestors are used against gas backflow and flashback at pipeline outlets and singlecylinder equipment.Super 85 for high flow
• the Flashback Arrestors can be installed independentof the orientation but according to gas flow
• each blowpipe should have its own Flashback Arrestor
• maximum ambient / working temperature is 70 °C / 158 °F
Maintenance
• annual testing of the non-return valve, leak tightnessand flow capacity is recommended
• WITT is happy to supply testing equipment
• Flashback Arrestors are only be serviced by the manufacturer. The dirt filter may be replaced by competent staff

and pipeline outlet points (hoses and any equipment) with high flow against dangerous reverse gas flow (RF85-10N-ES) and flashbacks
• without non-return valve (F85-10N-ES) for lower workingpressures with low pressure drop i.e. before and after analysers
• ideal for use with corrosive gases in the chemical industry,process technology or in the laboratory area
• WITT Flashback Arrestors may be mounted in any position / orientation
• the maximum ambient / working temperature is 70 °C / 158 °F
Maintenance• annual testing of the non-return valve, body leak
tight-ness 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
ApprovalsCompany certified according to ISO 9001:2000 and ISO 14001

• 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 forming explosive mixtures in the gas supply
• a filter at the gas inlet protects the arrestor against dirt contamination, extending the service life
Operation / Usage
• Flashback Arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks
• ideal for use with corrosive gases in the chemical industry, process technology or in the laboratory area
• for pipeline outlets and single cylinders with high users for example supply units for gas cutting machines
• 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
