Performance, Features & Benefits

• Long oil life – maintenance saving

Shell Corena S3 R is capable of providing oil maintenance intervals of 4,000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures of up to 100°C.

It is formulated to help:

• Resist formation of carbon deposits in sliding vane slots in vane compressors.
• Resist formation of deposits on rotating components in screw compressors.
• Resist thermal breakdown and deposit formation to 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, oil drain period below 4,000hrs is recommended (also consult OEM recommendations).

• Outstanding wear protection

With many years of successful application, Shell Corena S3 R helps provide effective 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.

• Maintaining system efficiency

Air release and prevention of foaming are critical performance characteristics in a compressor oil, ensuring reliable start-up and continuous compressed air availability.

Shell Corena S3 R 68 is designed to provide rapid air release without excessive foaming to give trouble-free operation even under cycling conditions.

In addition, Shell Corena S3 R 68 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 S3 R is suitable for use in oil-flooded/ oil injected single or two-stage rotary vane or screw air compressors.
