The pneumatic capability uses three compression stages arranged in cascade with ambient air being pumped to 110 psig by the first stage then to 450 psig in the second stage and, finally, to the third stage where it can be pumped to 600 psig if needed.

Three natural gas heaters and the required control circuitry provide hot air to selected test stations. Other test stations are dedicated to room temperature air testing.

The system is equipped with the required ancillary moisture and oil separators, having automatic drain provisions between the first and second stages, and between the second and third stages. the third stage air only requires oil filtration on its output.

A simplified system diagram is provided for your review. Since there are 13 test stations, a dual role is achievable for air or gas testing on an as-required basis. Whittaker has the capability to test either fluid as needed and can alternate easily between them. The maximum known gas requirement, 25,000 pounds per hour at 500 psia, will be easily achievable with minimal system modifications.
