7.5 Maintenance intervals
Caution:
The frequency of the maintenance intervals (oil
change, replacement of oil filter, fine separator
cartridge and air filter element) varies depending
on the application and the operating parameters.
Depending on the design of the system, mainte-
nance interval should therefore be specified by the
compressor manufacturer. These must be given
priority. It is advisable to conclude a maintenance
agreement. The following table provides an over-
view of the reference value for the screw compre-
sor module.

Once after 50 Bh Check shaft seal for leakage once after 50 operating hours
Every 100 Bh Check the shaft seal for leakage every 100 operating hours
Every 1,000 - 6,000 hours
depending on application,
