7.8 Maintenance intervals
Attention
The frequency of the maintenance intervals (oil change, replacement of oil lter, ne separator car-
tridge and air lter element) varies depending on the application and the operating parameters.
Depending on the design of the system, maintenance interval should therefore be specied by the
compressor manufacturer. These must be given priority. It is advisable to conclude a maintenance
agreement. The following table provides an overview of the reference value for the NK 31 screw com-
pressor module.
