FADAL MACHINING CENTERS
34 PRE-INSTALLATION PROCEDURES MAN-0126_R1
2.4 AIR SUPPLY WARNING!
Air pressure required: 120 psi before regulator, 80 psi after regulator, 15 scfm (stan-
dard cubic feet per minute) momentary.
1. From the main air supply line attach a 3/8” air supply line for the VMC. The distance
from the air compressor and number of machines attached should be taken into
consideration when determining the size of piping for the main air supply line.
2. Piping may consist of one or more of the following: galvanized pipe, PVC pipe or
high pressure hose. Do not use quick disconnects; quick disconnects will restrict air
flow.
3. A “T” riser should be used to connect the main air supply line with the air supply line
to the VMC (See Figure 2-4: Attach Drain to Lowest Point of Air Supply Line).
4. To prevent moisture from entering the VMC’s air system, attach a drain to the
lowest point of the air supply line. (See Figure 2-4: Attach Drain to Lowest Point of
Air Supply Line). The drain could be a self-relieving moisture separator, a simple
petcock, or a gate valve opened occasionally to release the water build-up. An air
dryer is preferred where higher moisture levels exist.
5. To help prevent contaminants from entering the air system on the VMC, place a
filter in-line on the main air supply line.
