Replacement Kaeser 9540900010 Air Compressor Lubricating Oil
How often should you change the compressor oil?
The air compressor maintenance schedule depends on a number of factors, including the type of machine, frequency of use, and whether it is used in an unheated environment.
- The user manual will have the manufacturer's recommended maintenance schedule, but if it is not found, follow the following guidelines.
- In general, rotary screw compressors are very efficient, so you only need to replace the lubricant after 4,000 to 8,000 working hours.
- Reciprocating compressors are not very efficient, so fresh oil may be required every three months or 200-300 hours (whichever comes first).
- Considering the temperature. If you plan to use your machine outdoors in winter or in a lukewarm store, it is best to use a thicker winter air compressor lubricant.
How to replace the air compressor lubricating oil?
Changing the oil in an air compressor is usually a simple process.
- First, run the machine for a few minutes to heat the oil and remove the filling cap to allow air to enter the system.
- Remove the oil plug, drain the old oil into the container, and slowly begin to pour the lubricant into the motor.
- You might have to add a little oil at a time, wait for it to circulate through the system, and then add more oil.

The benefits you can get
- Reduced downtime
- Reduced costs for replacement parts, oil filters and oil separators
- Longer oil life
- Prevents deposit on compressor parts
- Extended drain intervals
- Less evaporation
- Improved oxidation protection
- Reduced power consumption
- Improved thermal efficiency
- Improved mechanical efficiency
- Reduced friction
Proper lubrication can minimize friction. Since friction produces more heat and requires more energy to cool the equipment sufficiently to operate safely, less friction means less energy consumption and lower energy costs.
