Global Product Code: 001D7783



Application:

Shell Corena S3 R 68 is engineered for long-life, efficient lubrication in rotary sliding vane and screw air compressors. It is formulated for use in oil-flooded or oil-injected compressors, including single and two-stage units. The product performs reliably in high ambient temperatures and heavy-duty industrial applications, including in humid climates where oil drain intervals may be adjusted based on conditions.

Performance Features & Benefits:

  • Extended Oil Life: Supports oil maintenance intervals up to 4000 hours under typical conditions (check OEM and environmental recommendations).
  • Carbon Deposit Control: Resists carbon and lacquer formation in sliding vanes and screw rotors for cleaner operation.
  • Superior Wear Protection: Advanced ashless anti-wear chemistry helps protect internal surfaces, including bearings and gears.
  • Stable Operation: Rapid air release and low foaming characteristics support reliable compressed air delivery during cycling loads.
  • Efficient Water Separation: Maintains system performance in presence of water thanks to excellent demulsibility properties.

Main Application Areas:

  • Rotary sliding vane compressors (oil-injected/flooded)
  • Rotary screw compressors (single or two-stage)

Specifications & Approvals:

  • ISO 6743-3 L-DAH

Environmental & Safety Information:

  • Use appropriate protective equipment. Avoid prolonged contact with used oil. Wash thoroughly after handling.
  • Dispose of used oil in accordance with local regulations at approved collection points. Do not release into the environment.
  • Safety Data Sheet (SDS) available via inquiry
