Shell Corena S3 R is a premium quality air compressor oil designed to deliver high performance lubrication of  rotary sliding vane and screw air compressors. It uses an advanced additive system to provide excellent
protection and performance for compressors running with oil maintenance intervals of 4,000 hours and up to  6,000 hours under certain conditions.

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 1000C. This may be extended to up to 6,000 hours  under certain conditions.  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, the lower oil drain period of 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 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 has excellent water  separation properties to help ensure continuous efficient operation of the compressor even in the presence of water.
