Specific Oxygen version ref P4B.4051.... Reminder on the oxygen use
This oxygen version reference is designed and assembled taking into account the general rules, the state of
the art, to be applied on components that will be used with oxygen for industrial applications.
This version is using only oxygen compatible materials, but the material type is not the only factor in a typical
self ignition process. Flow speed for example, is a very important factor, and should be limited to 25 m/sec in
the whole application (attention to valve restriction).
Filtration also should be carefully implemented and maintained (a filter partially blocked will increase the flow
speed).
The final user should be familiar with these general rules that must be applied for oxygen applications, and is
responsible of the real conditions of use of our regulators.
