Shell Corena S3 R46 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 at up to 20 bar and 1000C discharge temperatures with oil maintenance intervals of up to 6000 hours.

• Long oil life – Maintenance savingShell Corena S3 R is capable of providing oil maintenance intervals of up to 6000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures of up to 1000C.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/airseparator and coalescer systems.• Exact oil maintenance interval will depend on  intake air quality, duty cycle and ambient conditions. For hot and humidtype climates as found in the Asian and Pacific regions, a reduced oil drain period is recommended (consult OEM recommendations)• Outstanding wear protectionWith 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 efficiencyAir 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.

  • Rotary sliding vane air compressorsShell Corena S3 R is suitable for oil-flooded or oil-injected vanecompressors, operating at pressures of up to 10 bar and with air discharge temperatures of up to 1000C.• Screw air compressorsSuitable for oil flooded or oil injected, single or two-stage rotarycompressors, operating at pressures of up to 20 bar and with air discharge temperatures of up to 1000C.Specifications, Approvals & Recommendations• ISO 6743-3A-DAJFor a full listing of equipment approvals and recommendations, please consult your local Shell Technical Helpdesk.Compatibility & Miscibility• Seal CompatibilityShell Corena S3 R oils are compatible with seal materialsspecified for use with mineral oils.
