SECTION 5
COMPRESSOR LUBRICATION – SEPARATION, FILTRATION AND
CONTROLS
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the compressor package before removing valves, caps, plugs,
fittings, bolts and filters.
High temperature operation can cause damage to equipment or personal injury.
Do not restart the unit repeatedly after high temperature shutdown. Find and
correct the malfunction before resuming operation.
COMPRESSOR OIL SYSTEM – Lubricating oil is employed to absorb the heat of compression, lubricate moving
parts and seal internal clearances between the rotor and air cylinder. Pressure differential between the air/oil
reservoir and various injection points is used to flow oil through the package.
Oil exits the air/oil sump and is then routed to the heat exchanger and the thermal mixing valve, where cold (oil
cooler branch) and hot (bypass branch) are mixed to a temperature that will avoid water vapor condensation
within the oil system. Tempered oil is sent to the oil filter for cleaning, then onto injection. The injected oil
absorbs heat from compression while progressing through the compression chamber and is then discharged back
into the oil separation chamber as a mixture of liquids and aerosols (oil) and gas (air).
Centrifugal action within the air/oil reservoir separates the bulk of the oil from the air, where it is collected and
readied for the next cooling cycle. The compressed air and aerosols continue through a coalescing filter, where
all but 2 ppm of oil is removed from the compressed air and discharged to the aftercooler.
RECOMMENDED LUBRICANT – The Gardner Denver compressor is factory-filled with AEON 9000SP lubricant.
This lubricant is formulated to the highest quality standards and is factory-authorized, tested and approved for use
in our rotary screw compressors. AEON 9000SP lubricant is available through your authorized Gardner Denver
compressor distributor.
OIL SPECIFICATIONS - The factory fill compressor lubricant is Gardner Denver AEON 9000SP lubricating
coolant for all-year-round operation. This is a polyalphaolefin (PAO) synthetic lubricant specially formulated for
rotary screw compressor service.
It is highly recommended that the lubricating oil be analyzed frequently in order to identify its quality and
remaining operational life. A sampling valve, located on the tubing between the oil filter and the injection
manifold, is provided for this purpose.
