9.15 Maintenance information and
lubricant recommendations for
stationary compressors
Lubricant recommendations
Please note that proper lubrication will considerably
increase the service life of your compressor unit.
According to regulations relating to the prevention of
accidents, use lubricants the properties of which meet
the requirements of the operating conditions on site.
Do not mix lubricating oils of different makes. When
changing over to a new oil type, drain the old oil
completely from the system.
If final compression temperatures of more than 90 °C/
195 °F occur continually, the oil change intervals given
in section 9.3 (maintenance schedule) are halved.
The oil change intervals should be calculated more
accurately in accordance with the actual operating
conditions by analyzing the oil.
Use the following oil type:
AEON Compressor Oils
AEON 3000 - Mineral
AEON 6000 - Food Grade (optional)
AEON 9000 - Synthetic (optional)
