SECTION 5
LUBRICATION
OIL COOLER, OIL FILTER & SEPARATOR
COMPRESSOR OIL SYSTEM
- Lubricating oil is employed to absorb the heat of compression, lubricate
moving parts and seal internal clearances between the rotor and the air cylinder. Pressure differential
between the air/oil sump and the final injection point into the compressor is used to move the oil mass
through the various oil system components. Refer to Figure 4- 8, page 50, for the arrangement of the oil
system components - they are highlighted in blue for identification ease.
Oil exits the air/oil sump and is delivered to the heat exchanger and thermal mixing valve, where cold (oil
cooler branch) and hot (oil bypass branch) are mixed to the desired (131ºF) injection temperature. The
tempered oil is cleansed via the oil filter before injection into the compressor casing.
RECOMMENDED LUBRICANT
- Gardner Denver compressors is factory filled with one of several
Gardner Denver AEO 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 standard factory fill compressor lubricant is Gardner Denver AEON 4000, a
superior semi-synthetic blend of petroleum stock and various protective additives, suitable for year-round
operation. For exceedingly high or low operating temperatures, see lubricant recommendations in this
and in Section 2, page 14.
OIL LEVEL INDICATOR (GAUGE)
indicates the amount of oil in the oil reservoir - See Fig 5-1 for details.
Read oil level when unit is in operation and stable (discharge pressure and temperature). In operation
the oil level will fluctuate as the compressor loads and unloads. Adequate oil level falls between the MAX
and MIN limits of the sight glass:
·
The approximate oil system total capacity is 3.3 Gals (12.5 L)
·
The differential between "MAX" and "MIN" levels on sight glass is 1.7 Gals (6.4 L).
·
Oil level may vary when air flow is modulated.
