Shell Corena S4

Real-world value delivery by Shell Corena S4 R

Users of Shell Corena S4 R across a wide range of industries are benefiting from changing to the oil. Customers are increasing production and cutting maintenance costs by

  • + Typically increasing oil-drain intervals by 100% compared with conventional oils
  • + Extending equipment service life: one cement company is running its compressors for three times longer between overhauls
  • + Reducing the high operating temperatures caused by thickening of the original oil, which prevented the oil valves from working efficiently.

Shell Corena S4 R oils are advanced, synthetic rotary air compressor oil

Shell Corena S4 R is the ultimate Shell sliding-vane and screw rotary air compressor oil. It uses an advanced, synthetic, ashless-technology formulation to provide extended oil and equipment life. It is an oil that you can rely on to help keep your highest temperature and pressure rotary air compressors working efficiently for longer, and thus provide enhanced compressed air availability for increased productivity.
It is widely recognised and approved by leading equipment manufacturers.

Shell Corena S4 R is designed to protect

Protecting compressors from damage can help to increase service life and maximise your return on investment. Shell Corena S4 R offers:

  • + Excellent protection across a wide temperature range, as it is 
  • + Up to 58% better four-ball weld-load performance compared with Shell Corena S3 R, as it passes at 270 kg.

Shell Corena S4 R is designed for long oil life

Limiting fluid degradation can help to prolong oil life. Shell Corena S4 R is designed to help you operate your compressors for longer without interruption – for reduced maintenance requirements and enhanced productivity. Shell Corena S4 R delivers

  • Up to 12,000 hours’ oil life in service*, which is over four times longer than Shell Corena S3 R, as demonstrated in extended Shell Hydrovane tests running at 120°C. This test is two to three times more severe than normal operations at around 100°C.
  • + Over three times the oil life compared with a premium air compressor oil such as Shell Corena S3 R in industry-standard oxidation tests.

Shell Corena S4 R are designed for system efficiency

Deposits, air bubbles in the oil and foaming can reduce rotary compressor efficiency. Shell Corena S4 R helps to maintain the constant supply of compressed air that you need for efficient operations by offering

  • + Over five times faster air release than Shell Corena S3 R, which helps to improve lubrication and prevent cavitation damage
  • + Over twice the water separation rate of Shell Corena S3 R, which helps to ensure efficient protection and lubrication.
