FAQ

What is the service life of this flashback arrestor and when should it be replaced?

Flashback arrestors are safety-critical components and should be inspected annually by a competent person. Replacement is typically recommended every 5 years, or immediately after a severe flashback incident, even if no external damage is visible.

Can this W000290701 arrestor be used for oxygen lines?

No, this model is specifically designated as ‘FG’ for Fuel Gas (like acetylene or propane) and is color-coded red. Oxygen systems require a different arrestor (typically blue or green coded) made from oxygen-compatible materials to prevent ignition risks.

What do the ‘BLW’ and ‘FG’ designations in the model name stand for?

‘BLW’ typically indicates that the arrestor is designed to be mounted on the blowpipe or torch (‘Brennersicherung’ in German). ‘FG’ stands for Fuel Gas, specifying its application.
