Our Mobil Rarus™ 400 Series ashless air compressor oils are designed for compressor systems employing gears and bearings, and are highly recommended for crankcases. They are formulated with high-quality mineral base oils and a high-performance additive system to provide exceptional equipment protection and reliability for compressors operating under mild to severe conditions. 

Mobil Rarus 400 Series air compressor oils can result in cleaner compressors and lower deposits compared to conventional mineral oils, resulting in: 

  • Longer running periods between maintenance intervals
  • Improved valve performance
  • Lower maintenance costs

Features and Benefits

Effective Rust and Corrosion Protection Improved protection of valves and reduced wear of rings and cylinders

The use of the Mobil Rarus 400 Series oils can result in cleaner compressors and lower deposits compared to conventional mineral oils, resulting in longer running periods between maintenance intervals. Their excellent oxidation and thermal stability safely allow extended life capability while controlling sludge and deposit formation. They possess outstanding anti-wear and corrosion protection, which enhances equipment life and performance.

Applications

The Mobil Rarus 400 Series oils are recommended for single and multistage air compressors. They are particularly effective for continuous high temperature operation. The maximum compressed air temperature, according to DIN 51506, is 220 °C. They are suitable for reciprocating and rotary type machines with the lower viscosity grades mainly used in rotary compressors. Rarus 400 Series oils are recommended for units with a history of excess oil degradation, poor valve performance or deposit formation. They are compatible with all metals used in compressor construction and with mineral-oil compatible elastomers used in seals, O-rings and gaskets.

 Mobil Rarus 400 Series oils are not intended or recommended for use in air compressors for breathing applications.

 The following types of compressors have shown excellent performance with the Mobil Rarus 400 Series oils:

  • Reciprocating air compressor crankcases and cylinders
  • Rotary screw compressors
  • Rotary vane compressors
  • Axial and centrifugal compressors
  • Compressor systems with critical gears and bearings
  • Compressors used in stationary and mobile applications
