Semi-Synthetic Compressor Oils 46 & 68 represent a cutting-edge solution for demanding compressor systems. These oils are crafted from a blend of exceptionally refined Group III base oil and a complex mixture of high-quality synthetic PAO oils, which boast an impressive viscosity index and low pour point. This unique combination ensures not only extended trouble-free service life but also unwavering chemical stability even in the harshest operating conditions. Additionally, they excel at safeguarding against corrosion, resisting emulsification, and preventing unwanted foam formation.

As compressor systems evolve to accommodate higher pressures while reducing equipment sizes, the lubricants in use must rise to the occasion. These industrious compressor oils face the formidable task of lubricating, sealing, and cooling critical components in the face of escalating temperatures, turbulence, and pressure. Furthermore, the demand for sustained performance across extended service intervals necessitates continuous advancement in additive systems.

To meet these exacting requirements, Semi-Synthetic Compressor Oils 46 & 68 have been meticulously formulated. They leverage synthetic polyalphaolefin and severely refined Group III paraffin base oils, enhanced with performance-boosting additives. This includes a specialized ashless multifunctional additive package designed to combat oxidation, rust, and wear. These oils exhibit unparalleled service life, even under the most extreme pressures and temperatures, ensuring they remain the preferred choice for modern compressor systems.


The performance benefits of Semi-Synthetic Compressor Oils 46 & 68 include:

  • Exceptional thermal and hydrolytic stability, ensuring reliable performance under high temperatures and exposure to water.
  • Very impressive oxidation stability, which extends the overall service life of the oil.
  • Good demulsibility and anti-foam properties, preventing undesirable water-oil mixtures and foam formation.
  • High load-bearing capacity, delivering outstanding extreme pressure (EP) performance.
  • Superior corrosion protection for both steel and non-ferrous metals.
  • Excellent filterability, minimizing the risk of filter blockage.
  • Reduced pump wear, enhancing the longevity of compressor equipment.

Semi-Synthetic Compressor Oils 46 & 68 meet or exceed the requirements of many international tests and specifications for industrial and mobile hydraulic and compressor systems including:
