8.1.9 Oil separation
The fine oil separation becomes poorer in the
upper area with an increasing screws-compressor
air end outlet temperature.
8.1.10 Multigrade oil
The use of multigrade oils can cause problems in
the long run, as "viscosity improvers" used are
destroyed over time. The oil is then no longer
secured in the upper viscosity class and a thermal
stability is no longer completely ensured. There-
fore, multigrade oils are not approved for use in
ROTORCOMP screw compressor air ends.
Caution:
Only use oils approved for screw compressor air
ends!
