Screw Type Compressor Oil

Performance Standard

  • Very good oil oxidation resistance
    Resists formation of carbon deposits in sliding vane slots, enabling them to move freely. Also resists deposit formation on rotating components of screw compressors. As a consequence, high levels of compressor efficiency can be maintained for long period in both types of compressors.
  • Very good air release and anti-foam properties
    The careful selection of base oils and additives provide rapid air release without excessive foaming to give trouble-free operation even under cycling conditions.
  • Very good rusting and wear protection
    Effectively protects all metal surfaces from corrosion. Protects all sensitive machinery parts, e.g. gears, screws, bearings from wear and prolongs the service intervals.
  • Internal cleanliness
    Coupled with the oil’s long life capability is its ability to maintain internal surface cleanliness in service. This is important to maintain high levels of performance for the compressors and separator/coalesce.
  • Improved water shedding properties
    Maintain performance when contaminated with water.

Benefits

  • Good seal compatibility
    For increased seal longevity and reduced leakages.
  • Low temperature performance
    For easy start-up at low temperature.
  • Yellow metal passivation
    Corrosion protection and longer component life.
  • Hydrolytic stability
    Prolongs oil life in moist condition.

Application

  • Rotary sliding vane air compressors
    Oil flooded or oil injected, single or two-stage compressors, operating at pressure of up to 10 bar and with air discharge temperatures of up to 100°C.
  • Screw air compressors
    Oil flooded or oil injected, single or two-stage compressors, operating at pressures of up to 20 bar and with air discharge temperatures of up to 100°C.
