CORENA S3 R 68

Shell Corena S3 R 68 is a premium air compressor oil formulated to provide high-performance lubrication for rotary sliding vane and screw air compressors. Its advanced additive system ensures excellent protection and performance, allowing for oil maintenance intervals of up to 4,000 hours, as recommended by manufacturers.

 

Key Features and Benefits:

  • Extended Oil Life: Designed to withstand maximum discharge temperatures up to 100°C, Shell Corena S3 R 68 resists the formation of carbon deposits in sliding vane slots and on rotating components in screw compressors. This resistance helps maintain internal surface cleanliness, particularly in oil/air separator and coalescer systems.
  • Outstanding Wear Protection: The oil contains an advanced ashless anti-wear system that effectively protects internal metal surfaces from corrosion and wear, thereby prolonging the life of critical parts such as bearings and gears.
  • Maintained System Efficiency: Shell Corena S3 R 68 offers rapid air release without excessive foaming, ensuring reliable start-up and continuous compressed air availability. Its excellent water separation properties help maintain efficient compressor operation even in the presence of water.

Applications:

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