Use only CLEAN containers and funnels to avoid contamination of oil. Provide
for clean storage of oils. Changing the oil will be of little benefit if done in a
careless manner
OIL CHANGE INTERVAL
– The AEON 9000SP Synthetic Lubricating Coolant shall be changed every 8000
hours of operation or as prescribed by the results of an oil analysis, whichever comes first. Note that severe
operating conditions (e.g., very dusty, high humidity, etc.), may require more frequent oil changes.
Gardner Denver offers a free oil analysis program with our AEON 9000SP lubricant. The first sample from a new
unit should be sent in between 40-100 hours of operation.
DRAINING AND CLEANING OIL SYSTEM
- Always drain the complete system. Draining when the oil is hot will
help to prevent varnish deposits and carry away impurities. To drain the system, use the following method:
1.
Be sure the unit is completely off and oil sump is depressurized.
2.
Disconnect lockout and tagout the power supply to the compressor package.
3.
Close (if provided by user) valve isolating compressor package from air system.
4.
Wipe away all dirt around the oil fill plug (1) and remove it.
5.
Remove drain (3) plug to evacuate oil.
6.
Replace drain plug (3), add oil up to the max level on the oil sight gauge, and replace fill plug (1).
7.
Restore power and run unit to check for leaks.
8.
After 1-2 minutes of operation, stop the unit, allow the oil to settle, and check that a proper oil level has been
achieved. If additional oil is required, repeat steps 1, 2, 3, 4, 6, and 7 to correct oil level.
9.
If the drained oil and/or the oil filter element are contaminated with dirt, flush the entire system, reservoir, oil
cooler, mixing valve and lines. Inspect the oil separator element for dirt accumulation; replace if necessary.
If a varnish deposit exists, contact the factory for recommendations for removal of the deposit and prevention
of varnish.
REFILLING OIL SYSTEM
- The steps to refill the drained oil system are the same as those already presented for
the addition of oil between changes – see page 37 for full details. The only exception in filling all the empty lines
and components (e.g., oil cooler, compressors, and oil filter) will be a much larger volume of oil required.
The VS11 package requires nearly 1.25 gallons of AEON 9000SP Synthetic Lubricating Coolant to fill all the lines
and components and achieve normal oil level.
COMPRESSOR OIL FILTER
- The oil filter is a vital part in maintaining a trouble-free compressor, since it
removes dirt and abrasives from the circulated oil. It should be replaced every 1000 hours of operation, sooner if
necessary due to dirty environment and when the oil is changed. See Figure 1-3, page 10, for the location of the
oil filter cartridge relative to the package hardware.
A flow bypass valve, mounted inside the filter cartridge, provides uninterrupted oil flow when the filter element is
contaminated and its backpressure exceeds 29-36 psid (at typical operating conditions of 167
°
F and 100 psi).
However, since this condition introduces unfiltered, potentially contaminated oil into the compressor, it is best
avoided by following the recommended filter replacement intervals.
