LUBRICATION
OIL COOLER, OIL FILTER & SEPARATOR
COMPRESSOR OIL SYSTEM - The compressor oil system cools the compressor, lubricates moving
parts and seals internal clearances in the compression chamber.
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 lubrication, 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
remaining mixture then passes through the final oil separator where most of the remaining oil is removed.
The separated oil is returned to the compressor and the air passes to the aftercooler.
RECOMMENDED LUBRICANT - Gardner Denver compressors are factory filled with AEON lubricants.
These lubricants are formulated to the highest quality standards and are factory authorized, tested and
approved for use in rotary screw compressors. AEON lubricants are available through your authorized
Gardner Denver compressor distributor.
OIL SPECIFICATIONS - The recommended compressor lubricant is Gardner Denver AEON 4000
Lubricating Coolant which can be used for year-round operation except as noted in the “High
Temperature Operation” (this section) or low temperature, see “Installation for Cold Weather,” Section 2,
page 10. AEON 4000 Lubricating Coolant is a superior petroleum base lubricant formulated and
containing additives for use in Gardner Denver compressors.
CAUTION
Specific AEON lubricants are recommended for use in this equipment. Other
lubricants may cause excessive carryover or compressor damage. Do not mix
different types of lubricants or use inferior lubricants.
Check the decal on the oil reservoir for lubricating coolant specification.
HIGH TEMPERATURE OPERATION - If the discharge temperature is sustained between 200-210
°
F for
a period of more than four (4) hours due to continuing high ambient air temperature, use Gardner Denver
AEON 9000 SP Lubricating Coolant which is a superior 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 4000.
COLD AMBIENT OPERATION - See “Installation for Cold Weather Operation”, Section 2, page 10 and
FIGURE 2-3, page 9.
PROCEDURE FOR CHECKING OIL LEVEL - Check the oil level when the compressor is shutdown and
the oil/air mixture has separated. The oil should be visible in the oil site gage (Figure 5-3, page 29).
ADDITION OF OIL BETWEEN CHANGES – Oil must be added when the oil level is not visible in the oil
site gage, as read when the unit is shutdown and the air/oil mixture has settled out to air and oil.
