DESCRIPTION AND THEORY OF OPERATION
EQUIPMENT DESCRIPTION AND DATA
Air System: Air Compressor Assembly and Two-Stage Air Filtration System (see Figure 18)
Air Compressor AC-1. A 3-stage air compressor that discharges air at approximately 5 cubic ft.
per minute and 1800 psig. The compressor is operated by a five horse-power electric motor.
Temperature Switch TSH-901. Shuts down the compressor if the compressor third-stage
temperature is too high.
Automatic Drain Valve XV-910. Opens automatically at 15-minute intervals to blow water from
the intermediate filter.
Coalescer CO-1. Located at the discharge of the compressor, CO-1 removes most of the water
and oil that may be contained within the air.
Drain Shutoff Valve V-902.
Automatic Drain Valve XV-911. Opens automatically at 15-minute intervals to blow water and
oil from the coalescer.
High-Pressure Air Relief Valve RV-901. Releases air when the air pressure exceeds 2200 psig
to protect the compressor and other high-pressure air system components.
Check Valve V-903.
Prevents filtered air from flowing back toward the compressor when the
compressor has cycled off.
Air Purification Filter AF-2. Removes any water and oil remaining in the air.
High-Pressure Air Vent Valve V-904. Used to vent high-pressure air before servicing the air
compressor or the two-stage air filtration system (CO-1 and AF-2).
