System gas requirements
Caution: 5 µm filtration is required on oxygen and nitrogen
supply lines. Failure to use an acceptable filter can
cause poor cut quality and damage to the laser system.

* Oxygen, nitrogen, and air are required to be connected at all times
** ISO standard 8573-1 Class 1.4.2 requirements are:
• Particulates – no more than 100 particles per cubic meter of air at a size of 0.1 to 0.5 microns in the largest
dimension and 1 particle per cubic meter of air at a size of 0.5 to 5.0 microns in the largest dimension.
• Water – the pressure dew point of the humidity must be less than or equal to 3° C (37.4° F).
• Oil – the concentration of oil can be no more than 0.1 mg per cubic meter of air.
*** If air will not be used as a cut gas, the required pressure and flow rate of the air supply can be reduced:
• Pressure: 500 kPa / 5 bar / 75 psi
• Flow rate: 25 slpm / 53 scfh
