Flashback Arrestors

Flashback Arrestors

Although working with fuel gases is a safe process in the hands of trained personnel, it can lead to a dangerous situation if the equipment is used incorrectly. Fuel gases should not be used unless proper safety procedures have been understood and applied. Special safety devices as flashback and flame arrestors according to DIN EN ISO 5175-1 prevent dangerous backfire and flashback.

WITT flashback arrestors / flame arrestors (FBA) are used to protect single cylinders, outlet points or pipelines and can be used for almost all technical gases such as acetylene, propane, propylene, ethylene, methane, hydrogen or oxygen.
