CORENA S4 R 46

Corena S4 R 46

Advanced Synthetic Rotary Air Compressor Oil

Shell Corena S4 R 46 is primarily an advanced synthetic air compressor oil designed to deliver the highest
performance lubrication of rotary sliding vane and screw air compressors. It uses a unique advanced additive
system to provide excellent protection and performance for compressors running with oil maintenance intervals of
10,000 hours and up to 12,000 hours under certain conditions. Shell Corena S4 R 46 is also perfectly suitable to
cover applications where a synthetic bearing & circulating oil or R&O oil (ISO VG 32-68) is required.

Performance, Features & Benefits

Long oil life – Maintenance saving ·
Shell Corena S4 R 46 is capable of providing oil maintenance
intervals of 10,000 hours (where allowed by manufacturers)
even when operating at maximum discharge temperatures
in excess of 1000C. This may be extended up to 12,000
hours under certain conditions.
The advanced formulation of Shell Corena S4 R 46 helps
deliver exceptional oil life through:
Exceptional resistance to thermal and chemical breakdown. ·
Resist formation of deposits on rotating components in
screw compressors and in sliding vane slots for continuous
efficient operation.
·Exceptionally low levels of deposit formation to help
maintain excellent internal surface cleanliness particularly
in oil/air separator and coalescer systems.

·The exact oil maintenance interval will depend on intake air
quality, duty cycle and ambient conditions. For hot and
humid type climates as found in the Asian and Pacific
regions, the lower oil drain period of 10,000hrs is
recommended (also consult OEM recommendations).

Outstanding wear protection ·
Shell Corena S4 R helps provide exceptional protection of
internal metal surfaces from corrosion and wear.
It contains an advanced ashless anti-wear system to help
prolong the life of critical parts such as bearings and gears.

· Shell Corena S4 R is designed to provide rapid air release
without excessive foaming to give trouble-free operation
even under cycling conditions helping to ensure reliable
start-up and continuous compressed air availability.
Shell Corena S4 R also has low volatility which can result in
lower evaporation and oil carryover in the compressor,
providing reduced oil top-up requirements in combination
with increased air quality.
In addition, Shell Corena S4 R has excellent water
separation properties to help ensure continuous efficient
operation of the compressor even in the presence of water.

Rotary sliding vane and screw air compressors ·
Shell Corena S4 R is suitable for use in oil-flooded/ oil
injected single or two-stage rotary vane or screw air
compressors.

Severe service conditions ·
May be used where exceptionally high ambient temperatures
or humidity are found.

Bearing & Circulating oil ·
Perfectly suitable to cover applications where a synthetic
bearing & circulating oil or R&O oil (ISO VG 32-68) is
required, and will provide benefits due to increased
resistance to deposits formation, improved low temperature
fluidity and lowering of equipment operating temperatures.
