Flashback Arrestor RF85-20N-ES Wittgas Vietnam

 

 

Product Information

WITT Flashback Arrestors provide reliable protection against dangerous reverse gas flow and flashbacks in compliance with DIN EN ISO 5175-1. Each unit undergoes 100% testing to ensure maximum safety and performance.


Key Advantages

  • Large-area stainless steel flame arrestor (FA): effectively extinguishes hazardous flashbacks entering the device from any direction.

  • Temperature-sensitive cut-off valve (TV): automatically shuts off and extinguishes sustained flashbacks before the device reaches critical internal temperatures.

  • Spring-loaded non-return valve (NV): prevents slow or sudden reverse gas flow that could otherwise form explosive mixtures in the gas supply line.

  • Integrated gas inlet filter: protects the arrestor from contamination, extending its service life.


Operation & Applications

  • Designed to safeguard gas cylinders and pipeline outlets (hoses and connected equipment) against reverse gas flow and flashbacks.

  • Ideally suited for corrosive gases used in the chemical industry, process technology, and laboratory environments.

  • Perfect for high-consumption outlets, such as supply lines for cutting machines.

  • Can be installed in any position or orientation.

  • Each flashback arrestor is designed for connection with a single device only.

  • Maximum ambient and operating temperature: 60 °C / 140 °F.

  • Suitable for gases such as acetylene, natural gas, LPG, hydrogen, oxygen, compressed air, and ethylene (others available on request).


Maintenance

  • Annual inspection recommended for non-return valve functionality, leak-tightness, and flow capacity.

  • WITT provides specialized testing equipment for proper inspection.

  • Maintenance must only be carried out by the manufacturer. The dust filter may be replaced by qualified personnel if required.
