Chapter 4 Maintenance
4.1 Lubricating Oil
The lubricating oil has a critical effect on the performance and service life of a screw air
compressor. If incorrect lubricating oil is used, it will cause severe damage to the
compressor. Either of the following compressor lubricating oils is recommended:
Option 1: Compressor Oil – Mineral Based
Brand: Castrol
Product: AIRCOL PD46
Service Life: Up to 2,000 Hours
Option 2: Synthetic Compressor Oil - Polyalphaolefin Based
Brand: Castrol
Product: AIRCOL SR46
Service Life: Up to 8,000 Hours
Equivalent premium grade compressor oils from other suppliers may be substituted.
Caution: Only use one or the other of the above recommended oil types. Do not
use a mixture of mineral and synthetic oils.
4.1.1 Oil Change Interval
a. The initial oil change should be performed after the compressor operates for about
500 running hours or 3 months, whichever occurs first.
b. If mineral lubricating oil is used, it should be replaced every 1,000 - 2,000 hours.
If synthetic oil is used, it should be replaced every 4,000 - 8,000 hours. In either
case, the lubricating oil should be replaced at least every 12 months if not sooner
according to the running hours limit.
c. If an oil sample analysis indicates that a lubricating oil change is required, it should
be replaced.
d. If the operating conditions are poor and the discharge temperature is high, the oil
change period should be shortened.
4.1.2 Replacing Oil and Oil Filter
a. Slowly close the air tank discharge valve to allow the compressor to operate in
unloading state for 3 minutes.
b. Shut down the compressor and switch off the power supply.
