pressure cylinders can be used to deliver compressed air or nitrogen, a high pressure regulator
should be fitted to either form of supply and be capable of delivering gas to the filter on the system
at a flow rate of 120 l/min at a pressure of 4�8 bar�

Gas quality
Clean, moisture-free, without oil
Note:
A poor quality gas supply has a detrimental effect on cut speeds, cut quality, reduced
thickness of material that can be cut and shorter consumable parts life�
WARNING
Do not allow the input gas pressure to exceed 10 bar/145 psi�
The filter bowl could explode if the pressure is exceeded�
