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 filtered to remove all oil or grease. Oil or grease
contamination from compressed or bottled air can cause fires in conjunction with oxygen.
For filtering, a coalescing filter able to filter to 0.01 microns should be placed as close as
possible to the gas inlets on the Gas Control Module.
