What Is Mobil Rarus 827?

Mobil Rarus 827 is a compressor lubricant formulated for industrial air compressor systems requiring higher viscosity oil to maintain proper lubrication film strength under heavy load conditions.

Lubricants in this viscosity range are commonly used in compressors where operating temperatures, pressure loads, or equipment design require stronger lubrication film protection than lower-viscosity oils.


Benefits of ISO 100 Compressor Oil

An ISO 100 compressor oil provides several benefits in demanding compressor environments:

  • Strong lubrication film strength for high-load compressor components
  • Improved wear protection for rotors, bearings, and internal parts
  • Reliable lubrication under elevated operating temperatures
  • Reduced metal-to-metal contact in heavy-duty compressor systems
  • Stable viscosity performance in industrial compressor applications
