Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks according to 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
● 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 (only 85-10)
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
● For pipeline outlets and single cylinders with high users for example supply units for gas cutting machines: Model 85-10
● For torches or burners with high flow: Models 85- 10NU and 85-10 eccentric = eccentric outlet
● For cutting machines with high flow: Model 85-10U
● 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
Maintenance
● Annual testing of the non-return valve, body leak tightness and flow capacity is recommended
● We are happy to supply special test equipment
● Flashback Arrestors are only to be serviced by the manufacturer; the dirt filter may be replaced according to model by competent staff
