Shell Corena AP - Parsian Super Lubricants

Shell Corena AP
Top tier quality reciprocating air compressor lubricant
Shell Corena AP is a top-tier reciprocating air compressor lubricant. It is
based on synthetic ester fluids and incorporates the latest additive technology
to provide the highest possible performance.
Applications
All industrial reciprocating air compressors
(Specially recommended for reciprocating
compressors operating at continuous high
pressure (30 bar and over) and high
temperature (discharge at 180°C).
Shell Corena AP may be used in
machines compressing air for breathing
purposes (such as air bottles for divers),
provided the installation itself is suitable
for this purpose.
Performance Features
Superior lubrication performance
In all operating conditions, including the
most demanding operations where mineral
oils are unsatisfactory
Long maintenance intervals
The absence of deposit formation enables
the normal valve cleaning process, typically
between 250 and 1,000 hours of operation,
using conventional mineral oils, to be
extended to 2,000, or even 4,000 hours.
Outstanding performance in all
operating conditions
Including reciprocating compressors
subjected to overloading, intermittent or
continuous operation, poor installation, high
compressor room temperatures
Increased safety
Absence of deposit formation has a very
important safety-related benefit. It is
common for pipework in an old installation
to be virtually choked with carbon. This
carbon deposit material is inflammable, and
fires and explosions can occur under
certain circumstances. In the past such
explosions have been known to cause
damage and loss of life.
Reduced costs
The very long maintenance intervals
effectively reduce 'down-time' and
manpower costs.

Seal Compatibility
Shell Corena AP, in common with other esterbased
lubricants, is not compatible with all
seal materials, and some older compressors
may need to have the seals changed before
they can be run on the new grades.

Breathing Air
Shell Corena AP may be used in machines
compressing air for breathing purposes (such
as air bottles for divers) provided strict
conditions are adhered to. All compressor
units for such purposes should include
subsidiary air clean-up apparatus following the
compressor, to ensure that the produced air is
fit for breathing.
Running-In
Shell recommend that mineral oils are used
for running-in new equipment in accordance
with manufacturers' recommendations,
typically this will be for 100 hours followed by
oil filter replacement and the oil change.
Health & Safety
Shell Corena AP is unlikely to present any
significant health or safety hazard when
properly used in the recommended
application, and good standards of industrial
and personal hygiene are maintained.
After skin contact, wash immediately with
soap and water.
For further guidance on Product Health &
Safety refer to your Shell Representative.
Protect the environment
Take used oil to an authorised collection point.
Do not discharge into drains, soil or water.
