5.6 Primary Pneumatic Services
Air inlet (q) - Located on the P-Box and provides an inlet to house compressed air source.
Recommended minimum air pressure requirement is ~50psi / 3.4bar. Somewhat higher inlet
pressures may be required, as needed, to generate higher flow rates or to drive pneumatic
instruments.
Do not exceed 90 psi / 6.1 bar on the Air inlet
Exhaust/ vacuum line (r) - Located on the P-Box. Leaving the Exhaust outlet open to the
atmosphere or connected to a vacuum line, will depend on the type of process vessel used.
For a vessel that cannot be pressurized (e.g., some stainless steel vessels, glass vessels, SUB,
etc.), the line is connected to a vacuum source. For a vessel that is pressure rated, one may
use vessel pressure to drive the Exhaust cycle, particularly at low XCell™ ATF System flow
rates; but in case where vessel pressure is limited, or at high XCell™ ATF System flow settings,
a vacuum source supplement may be required.
Note: In addition to vessel pressure, the hydrostatic pressure generated by the height difference between
vessel liquid level and pump level may assist or hamper the exhaust flow
