Castrol Aircol SR 68 is a polyalphaolefin-based
synthetic compressor oil, using an advanced additive
system to enhance thermal and oxidation stability
and reduce component wear. This product is
intended for use in Marine turbochargers and rotary
compressors, where it will provide significant
in-service benefits when compared with other
mineral and synthetic based lubricants. It is
approved as a Special Low Friction Synthetic Oil
by ABB Turbo Systems Ltd and is therefore
required in certain ABB VTR 4 series
turbochargers.


FEATURES AND BENEFITS


TCastrol Aircol SR 68 is a synthetic compressor oil for
use in dedicated turbocharger lubricant systems and
in rotary screw compressors.
Aircol SR 68 provides significant benefits when used
as a system oil in separately lubricated
turbochargers, where extended oil change intervals
will be possible. ABB Turbo Systems Ltd have tested
Castrol Aircol SR 68 and have approved it as a
Special Low Friction Synthetic Oil (SLFSO).
Aircol SR 68 is therefore approved for up to 5000
hours drain intervals and as a low friction lubricant,
the use of which is mandatory in certain ABB VTR 4
series turbochargers.
Aircol SR 68 is also particularly suitable for use in
oil-flooded rotary screw compressors. It has
outstanding oxidation stability and antiwear
performance. The ester-free formulation eliminates
acidic corrosion resulting from hydrolysis.
The performance of Castrol Aircol SR 68
compressor oil offers the following specific
benefits:
                v Extended service intervals
         v Reduced maintenance
           v Extended drain periods
  v Cleaner operation
v Reduced friction
Aircol SR is not suitable for use in Reciprocating Air Compressors, for which Aircol SN is recommended
