( Previously named: Shell Corena D )

Reliable compressor oil for rotary screw and vane air compressors

  • Formulated to provide oil maintenance intervals of up to 4000 hours

  • Resists carbon and deposit formation in sliding vane slots and screw rotors

  • Maintains cleanliness in separators and coalescers for efficient operation

  • Offers outstanding protection against corrosion and mechanical wear

  • Rapid air release and low foaming characteristics for stable performance

  • Facilitates efficient water-oil separation in compressed air systems

  • Suitable for use in rotary vacuum pumps and mobile compressor units

  • Compatible with seals designed for mineral oils

  • Formerly known as: Shell Corena D

Global Product Code: 001D7777



Application:

Shell Corena S2 R 68 is a high-quality air compressor oil developed for oil-injected rotary screw and sliding vane air compressors operating at up to 15 bar and 100 °C air discharge temperatures. It is suitable for stationary and mobile compressors, including those used in harsh environments such as construction sites and railways. The product may also be used in rotary and sliding vane vacuum pumps within compatible pressure ranges.

Performance Features & Benefits:

  • Extended Oil Drain Intervals: Provides up to 4000 hours of operation (based on operating conditions and OEM guidance).
  • Clean Running: Reduces carbon and lacquer formation, especially in vane slots and on screw rotors.
  • Reliable Protection: Anti-wear additives help extend the life of critical compressor parts like gears and bearings.
  • Stable Performance: Ensures quick air release and minimal foaming, even under cycling conditions.
  • Efficient Water Separation: Allows fast demulsibility and easy condensate handling in separator systems.

Main Application Areas:

  • Rotary sliding vane air compressors (oil-flooded or oil-injected)
  • Rotary screw compressors operating at up to 15 bar and 100 °C
  • Rotary and sliding vane vacuum pumps (except ultra-high vacuum)

Specifications & Approvals:

  • ISO 6743-3:2003 (DAH)
  • Widely used and approved by major OEMs

Environmental & Safety Information:

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