LUBRICATION
OIL COOLER, OIL FILTER & SEPARATOR
COMPRESSOR OIL SYSTEM
(Figure 5-3, page 69) 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 reservoir. 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 air 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 final discharge line.
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 factory fill compressor lubricant is Gardner Denver AEON 9000SP lubricating
coolant which can be used for year-round operation. AEON 9000SP is a synthetic, extended life lubricant
which can extend lubricant change intervals up to 4 times that of a petroleum based lubricant.
A lubricant analysis program for a periodic check of lubricant quality and remaining life can maximize the
change interval.
Use of improper lubricants will cause damage to equipment. Do not mix
different types of lubricants or use inferior lubricants.
Improper equipment maintenance with use of synthetic lubricants will damage
equipment. For oil filter and oil separator change intervals, see Maintenance
Schedule, page 79.
