Air System: Section 6 (see Figure 22)
Coalescer CO-2. Removes any remaining moisture from the 100 psig air that is coming directly
through Air System Section 3 from Air System Section 1. Air leaving CO-2 goes to the Feed Flow
Control Panel, Filtrate Flow Control Valve V-202, and the Air Manifold Assembly in the
Instrument/Solenoid Panel Box.
Low Pressure Air Shutoff Valve V-909. Used to shut off 100 psig air so maintenance can be
performed on the Feed Flow Control Panel, Filtrate Flow Control Valve V-202, or the Air Manifold
Assembly.
Low Pressure Air Vent Valve V-910. Opened as needed to bleed the air from the entire air
system.
