Manufacturer's description

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

Applications

• Rotary vane compressors and screw air compressors
• Shell Corena S4 R is suitable for use in single- or two-stage oil-flooded/oil-injected screw or rotary vane air compressors.
• Severe operating conditionsCan be used where exceptionally high ambient temperatures or humidity are encountered.
• Bearing and circulating system oilPerfectly suited to cover applications where a synthetic bearing and circulating oil or R&O oil (ISO VG 32-68) is required, and will deliver benefits through increased resistance to deposit formation, improved low-temperature fluidity and lower equipment operating temperature.

Performance & benefits

• Long service life – reduced maintenanceShell Corena S4 R is capable of delivering oil maintenance intervals of 10,000 hours (where permitted by manufacturers), even when operating at maximum discharge temperatures above 100 0 C. This can be extended to 12,000 hours under certain conditions. The advanced formulation of Shell Corena S4 R helps ensure an exceptional oil life through:
• Resists the formation of deposits on the rotating components of screw compressors and in vane slots, for continuous efficient operation.
• Very low levels of deposit formation, to maintain excellent cleanliness of internal component surfaces, particularly in oil/air separators.
• The maintenance interval depends on the quality of the intake air, the duty cycles and the ambient conditions. For the hot, humid climate of the Asia-Pacific regions, a reduced maintenance interval of 10,000 hours is recommended (consult the OEM recommendations).
• Exceptional wear protectionShell Corena S4 R helps ensure exceptional protection of internal metal surfaces against corrosion and wear. It contains an advanced, ashless anti-wear system that helps extend the life of critical parts such as the drive and bearings.
• Maintaining system efficiencyShell Corena S4 R is designed to ensure rapid air release without excessive foaming, delivering trouble-free operation even under cyclic duty and ensuring the availability of compressed air at start-up and continuously thereafter. Shell Corena S4 R also has low volatility, which can result in lower evaporation and oil carry-over in the compressor, giving reduced oil top-up requirements combined with improved air quality. In addition, Shell Corena S4 R has excellent water separation properties, to ensure the compressor continues to operate efficiently even in the presence of water.
• Excellent resistance to thermal and chemical breakdown
