Atlas Copco PAROIL


PAROIL from Atlas Copco delivers outstanding performance:


  • Excellent water separation
    Emulsified water in oil reduces the flow to lubricating points, encourages the formation of harmful deposits, and damages the bearings. To prevent this PAROIL permits easy separation and drainage of any condensed moisture in the compressor.
  • High oxidation resistance
    Atlas Copco PAROIL contains premium quality antioxidant additives. These help to minimize deposits and the formation of sludge and contaminants that tend to build up under very high temperatures. PAROIL long-life detergent additives keep the compressor internals clean and prevent contaminants from clogging the filter elements.
  • Balanced composition
    PAROIL combines superior heat absorbing and release characteristics for cooler running with excellent antifoaming. The latter ensures the rapid separation of air and lubricant in the compressor oil separator, keeps the oil clean, and prevents blocking of the oil separation filter, guaranteeing a low oil carry-over.
  • Superb anti-wear performance
    PAROIL reduces the adverse effects of moisture contamination with powerful anti-corrosion characteristics to protect the seals, bearings, and rotors of the compressor. PAROIL has high chemical stability and rust-inhibiting additives to further protect bearings and moving parts from acidic attack. Where longevity counts, PAROIL delivers.


Atlas Copco PAROIL compressor oil is supplied in three container sizes to suit customer requirements.
