Air Regulator Maintenance Guidelines
Some E XATRON Changeover Kits use compressed air. If your kit does use compressed air, it will also
require an air regulator. A high quality air regulator with coalescing air filter and shutoff valve is supplied
as part of your changeover kit. NEVER operate any E
XATRON equipment which requires
compressed air without an approved air regulator and shutoff valve.
Please refer to F IGURE 7-2 following this section for air regulator mechanical details. Additionally, please
refer to the manufacturer's data sheet in Chapter 10 of this manual if necessary.
The air regulator assembly consists of:
W ILKERSON A IR R EGULATOR , PART #NC00-440, AND
C OALESCING A IR F ILTER , PART #GPA-97-075.
1. Check the operation of the orange shutoff valve once a month:
Turn the valve OFF and verify that the air is indeed off. Turn the valve back ON.
2. Check the PSI setting:
Some special-case changeover kits may require less than 80 PSI . However, in general, set
the air regulator to 80 PSI , +/- 3 PSI.
3. Inspect the moisture trap chamber and the coalescing filter chamber. Verify that they are
clean, empty and dry. There should be no oil and no water in either chamber. If they are
dirty, physically disconnect the incoming air pressure supply from the air regulator and clean
the trap and filter as needed.
If you find it necessary to clean the trap and/or filter more often than once a month, you should correct the
problem at your in-house air compressor. Check your manufacturer's manual for the exact procedure
necessary.
