Category:

Shell Corena S4 R 68

Synthetic rotary air compressor oil for screw and vane compressors in extreme environments

  • Enables oil drain intervals of 10,000 to 12,000 hours under recommended conditions

  • Resists thermal and chemical breakdown at discharge temperatures above 100 °C

  • Minimizes internal deposit formation for cleaner compressors and separators

  • Protects against corrosion and mechanical wear with ashless additive system

  • Promotes rapid air release and minimizes foaming during cyclic operation

  • Offers low volatility for reduced oil consumption and high air quality

  • Excellent demulsibility supports reliable water drainage in humid settings

  • Also suitable as synthetic R&O or bearing and circulating oil (ISO VG 32–68)

  • Approved by ABB for use in VTR turbochargers (up to 5,000 hours)

Global Product Code: 001D7787



Application:

Shell Corena S4 R 68 is a synthetic lubricant developed for rotary sliding vane and screw compressors used in demanding industrial conditions. It is ideal for compressors operating in hot and humid environments or where extended oil drain intervals and high reliability are essential. Additionally, it can be used in systems requiring synthetic R&O or bearing and circulating oils with ISO VG 32–68 classifications. Approved for use in ABB VTR turbochargers (5,000-hour interval).

Performance Features & Benefits:

  • Extended Oil Life: Delivers oil drain intervals of 10,000 hours, extendable to 12,000 hours under clean intake air and favorable duty cycles.
  • Thermal and Oxidation Stability: Resists degradation at discharge temperatures above 100 °C for reliable, long-term operation.
  • Clean Operation: Prevents deposits on rotors, vane slots, and coalescers, ensuring efficient air/oil separation.
  • Outstanding Wear Protection: Ashless anti-wear additives guard bearings and metal surfaces from wear and corrosion.
  • System Efficiency: Provides rapid air release and reduced foaming for consistent startup and operation.
  • Low Volatility: Reduces oil carryover and top-up frequency, improving compressed air quality.
  • Water Handling: Excellent water separation prevents emulsions and supports clean drainage in humid conditions.

Main Application Areas:

  • Rotary sliding vane and screw air compressors (single or two-stage)
  • Systems operating in extreme temperature and humidity conditions
  • Applications requiring synthetic R&O or bearing and circulating oil (ISO VG 32–68)
  • Approved use in ABB VTR turbochargers (up to 5,000-hour oil interval)

Specifications & Approvals:

  • ISO 6743-3 L-DAJ
  • ABB VTR Turbochargers – 5,000-hour interval

Environmental & Safety Information:

  • Use impervious gloves and avoid skin contact. Wash thoroughly with soap and water after handling used oil.
  • Do not release into soil, drains, or waterways. Dispose of via authorized collection points.
  • Safety Data Sheet (SDS) available via inquiry
