Advanced Synthetic Rotary Air Compressor Oil

Shell Corena S4 R is primarily an advanced synthetic air compressor oil incorporating a unique high performance additive system. It is designed to deliver the highest performance lubrication of rotary sliding vane and screw aircompressors.
It uses an advanced additive system to provide excellent protection and performance for compressors running at pressures over 25 bar and in excess of 100ºC discharge temperatures with oil maintenance intervals of up to 12,000 hours. Shell Corena S4 R is also perfectly suitable to cover applications where a synthetic bearing & circulating oil or R&O oil (ISO VG 32-68) is needed.

DESIGNED TO MEET CHALLENGES

Performance, Features & Benefits

- Long oil life – Maintenance saving
Shell Corena S4 R is capable of providing oil maintenance intervals of up to 12,000 hours
(where allowed by manufacturers) even when operating at maximum discharge temperatures in excess
of 100ºC

The advanced formulation of Shell Corena S4 R 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.

- Outstanding wear protection

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 has low volatility and oil carryover to provide reduced oil top-up requirements in combination with increased air quality.

-  Maintaining system efficiency
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 has low volatility and oil carryover to provide 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.

Main Applications

- Rotary sliding vane and screw air compressors
Shell Corena S4 R is suitable for oil-flooded/oil injected, single or two-stage compressors, operating at pressures of in excess of 25 bar and with air discharge temperatures of over 100ºC
(including intermittent operation under these conditions).

- Severe service conditions
May also be used where exceptionally high ambient temperatures are found, when the oil temperature cannot be reduced to normal levels.

- ABB Turbochargers
The product is recommended for use in ABB turbochargers fitted to low and medium speed diesel engines used in marine and power generation applications.

- 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 deposit formation, improved low temperature fluidity, and lowering equipment operating temperatures.

When a higher viscosity grade synthetic oil is required we recommend to use Shell Morlina S4 B grades
for such applications. 

Specifications, Approvals & Recommendations

Compatibility & Miscibility

- Miscibility
Shell Corena S4 R oils are fully miscible with mineral oils, although dilution with mineral lubricants will markedly reduce its performance.
Care must be taken to avoid mixing Shell Corena S4 R with certain other types of synthetic fluids.
Contact your Shell representative for further information.

- Seal Compatibility
Shell Corena S4 R oils are compatible with seal materials specified for use with mineral oils. 

Health, Safety & Environment

- Health and Safety

Shell Corena S4 R Oil is unlikely to present any significant health or safety hazard when properly used
in the recommended application and good standards of personal hygiene are maintained.

Avoid contact with skin. Use impervious gloves with used oil. After skin contact,
which immediately with soap and water.

Guidance on Health and Safety is available on the appropriate Material Safety Data Sheet, which can be
obtained from http://www.epc.shell.com/

- Protect the Environment
Take used oil to an authorised collection point. Do not discharge into drains, soil or water.
