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 47, for full details. The only exception is
that to fill all the empty lines and components (e.g., oil cooler, compressors, and oil filter) a much larger
volume of oil will be required
The VS135-170 package requires nearly 26 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 within the package.
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
140
°
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.
Improper oil filter maintenance will cause damage to equipment. Replace filter
element every 1000 hours of operation. More frequent replacement could be
required depending on operating conditions. A filter element left in service too
long may damage equipment.
The filter media is contained within an easily replaced, spin-on cartridge. Use the following procedure to
replace the filter. Do not disturb the piping:
1. Be sure the unit is completely off and that the oil sump is depressurized.
2. Disconnect, lockout and tagout the power supply to the compressor package.
3. Close (when provided) valve isolating compressor package from air system.
4. Unscrew the cartridge with adequate tool (e.g., strap wrench) and remove.
5. Clean (wipe) and lubricate sealing surface on filter housing with grease.
6. Lubricate o-ring seal on new element with grease.
7. Screw-new element onto filter head firmly
– approximately 3/4 turns after cartridge and head make
contact.
8. Open isolation valve (when provided), restore power, then run unit to check for leaks.
OIL MIXING VALVE (Electronic)
– This device mixes cold (from oil cooler) and hot (bypassed) oil in
order to achieve a compressor discharge temperature above the saturation level of the water vapor
contained in the compressed air
– thus avoiding water collection in the oil system.
