2.09 Gas Requirements
The customer will provide all gases and pressure regulators. Gases must be of high quality. Pressure regulators
shall be equipped with stainless-steel diaphragms and installed as close as possible to the Gas Console. Specify Dual
Stage Stainless diaphragm regulators for hi-pressure cylinders (> 400 inlet psi) (example: Victor VTS-450-D-500,)
Single stage Station-stainless diaphragm regulator for low pressure (< 350 inlet psi) liquid or bulk tank supply
application (example Victor # LC-350DR).

Note 1: The air source must be adequately fi ltered to remove all oil or grease. Oil or grease contamination from
compressed or bottled air can cause fi res in conjunction with oxygen.
For fi ltering, a coalescing fi lter able to fi lter to 0.01 microns should be placed as close as possible to the gas inlets
on the Gas Control Module.
Note 2: The tap water source does not need to be deionized, but in water systems with extremely high mineral
content a water softener is recommended. Tap water with high levels of particulate matter must be fi ltered.
