LUBRICATION,
OIL COOLER, OIL FILTER & SEPARATOR
COMPRESSOR OIL SYSTEM (FIGURE 5–1, page
35) cools the compressor, lubricates moving parts and
seals internal clearances in the compression chamber.
The oil inlet line is connected at the bottom of the oil res-
ervoir. Air pressure in the oil reservoir forces oil through
the oil cooler, thermostatic mixing valve, oil filter and
into the compressor main oil gallery.
The oil passes through internal passages for lubrica-
tion, cooling and sealing. The air–oil mixture is then
discharged to the oil reservoir where a large part of
the entrained oil drops out of the air stream; the air
then passes through the final oil separator where most
of the remaining oil is removed. The separated oil is re-
turned to the compressor and the air passes to the final
discharge line.
RECOMMENDED LUBRICANT – Gardner Denver
compressors are factory filled with AEON
t
lubricants.
These lubricants are formulated to the highest quality
standards and are factory authorized, tested and ap-
proved for use in rotary screw compressors. AEON
t
lubricants are available through your authorized Gard-
ner Denver compressor distributor.
OIL SPECIFICATIONS – The recommended com-
pressor lubricant is Gardner Denver AEON
t
4000 Lu-
bricating Coolant which can be used for year–round op-
eration except as noted in the ”High Temperature
Operation” paragraph below, or low temperature, see
”Installation for Cold Weather,” Section 2, page 4.
AEON
t
4000 Lubricating Coolant is a superior petro-
leum base lubricant formulated and containing addi-
tives for use in Gardner Denver compressors.
Use of improper lubricants will cause
damage to equipment. Do not mix dif-
ferent types of lubricants or use infe-
rior lubricants.
HIGH TEMPERATURE OPERATION – If the dis-
charge temperature is sustained between 200–210
_
F
for a period of more than four (4) hours due to continu-
ing high ambient air temperature, use Gardner Den-
ver
R
AEON 9000 SP Lubricating Coolant which is a su-
perior synthetic lubricant. Short periods of up to four (4)
hours of sustained discharge temperatures up to 210
_
F do not require a change from the recommended
year–round lubricant AEON
t
4000.
LUBRICANT CHANGE PROCEDURE – Upgrading to
a longer life lubricant is essentially a very worthwhile
practice. Following are the primary steps to be com-
pleted when upgrading or changing the type of lubri-
cant.
1.
Thoroughly drain the system:
–
Drain oil from air end and cooler while hot.
–
Break low point connections and drain oil
from pipe runs.
–
Dump Oil from filter and reinstall used filter.
2.
Fill the system with a 50 percent charge of the new
lubricant:
–
Start the machine and stay there to observe.
–
Allow the machine to run about five minutes
at temperature, or until temperature stabi-
lizes, then shut down.
3.
Thoroughly drain the machine.
4.
Change to a new filter and separator.
5.
Fill the system with a full charge of the new lubri-
cant.
6.
Replace the drain plug before restoring power.
7.
The machine should then be run normally, howev-
er, total run time after the initial changeout should
be 50 percent of normal anticipated service life of
the new lubricant.
–
Drain all lubricant from the system, change
the filter and separator, and replace with a full
charge of the new lubricant.
8.
Subsequent lubricant changouts should be at nor-
mal intervals. (See Oil Change Interval chart,
FIGURE 5–3, page 37.)
