Shell Corena S4 R 46

Shell Corena S4 R 46 is an advanced synthetic rotary compressor oil designed for long-life lubrication in vane and screw compressors under severe operating conditions, delivering up to 12,000-hour oil drain intervals, outstanding cleanliness, and superior wear protection.

Category:

Shell Corena S4 R 46

Premium synthetic oil for rotary sliding vane and screw air compressors

  • Supports extended oil drain intervals of up to 12,000 hours (OEM and condition dependent)

  • Excellent resistance to thermal and chemical degradation above 100 °C

  • Helps minimize deposits in vanes, rotors, and separator/coalescer systems

  • Ashless anti-wear additives protect critical metal components

  • Ensures rapid air release and low foaming under cyclic operation

  • Low volatility minimizes oil top-up and improves air quality

  • Excellent water separation for reliable performance in humid conditions

  • Suitable also for synthetic R&O or bearing/circulating oil applications (ISO VG 32–68)

Global Product Code: 001D7786



Application:

Shell Corena S4 R 46 is a premium synthetic air compressor oil formulated for use in rotary sliding vane and screw compressors operating under severe conditions. It is suitable for oil-flooded or oil-injected single and two-stage compressors, and also performs as a synthetic R&O or bearing and circulating oil in systems requiring ISO VG 32–68 performance. Ideal for use in high-temperature and high-humidity environments, it supports long oil life while maintaining system cleanliness and efficiency.

Performance Features & Benefits:

  • Extended Drain Intervals: Enables oil change intervals up to 10,000–12,000 hours depending on OEM and environmental conditions.
  • High-Temperature Stability: Withstands operation at discharge temperatures exceeding 100 °C without degrading.
  • Cleaner Operation: Helps prevent deposit build-up in screw rotors, vane slots, oil/air separators, and coalescers.
  • Superior Wear Protection: Ashless formulation protects bearings and gears from wear and corrosion.
  • Low Oil Consumption: Low volatility minimizes evaporation losses and reduces oil carryover.
  • Excellent Demulsibility: Efficiently separates water to prevent emulsions and ensure clean condensate drainage.

Main Application Areas:

  • Rotary screw compressors (single or two-stage)
  • Rotary sliding vane compressors (oil-injected/flooded)
  • Severe service environments with high ambient temperature and humidity
  • Applications requiring synthetic R&O or bearing and circulating oils (ISO VG 32–68)

Specifications & Approvals:

  • ISO 6743-3 L-DAJ

Environmental & Safety Information:

  • Use impervious gloves and wash exposed skin immediately after contact with oil.
  • Do not release into soil, drains, or watercourses. Dispose of used oil via approved collection systems.
  • Safety Data Sheet (SDS) available via inquiry
