Mobil Rarus SHC™ 1020 Series air compressor oils

Air Compressor Lubricant

Mobil Rarus SHC™ 1020 Series
Ratings

Our Mobil Rarus SHC™ 1020 Series synthetic air compressor oils are designed to lubricate severe-duty rotary screw and vane air compressors. These outstanding synthetic air compressor oils are particularly suited for severe service applications where mineral products are not as effective.

Mobil Rarus SHC 1020 Series synthetic air compressor oils are formulated for excellent wear protection and resistance to oxidation and thermal degradation. These lubricants outperform mineral oils and help to:

  • Minimize downstream deposits and carryover
  • Reduce the potential for fires and explosions
  • Improve equipment performance and safety
  • Reduce maintenance needs and associated costs

Applications

The Mobil Rarus SHC 1020 Series oils are primarily intended for rotary screw and vane compressors. They are particularly effective for continuous high temperature operation with discharge temperatures up to 200º C. Rarus SHC 1020 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 conventional mineral oil-based air compressor oils but admixture with other oils may detract from the total performance capability.

 

Mobil Rarus SHC 1020 Series oils are not recommended for air compressors used in breathing air applications and should not be used in compressors where the discharge temperature is higher than the product flash point.

 

The following types of compressor applications have shown excellent performance with the Mobil Rarus SHC 1020 Series oils:

     •  Primarily recommended for rotary screw and vane air compressor

     •  Very effective in screw type compressors with oil injection cooling

     •  Units operating under severe conditions

     •  Multistage units with a history of excessive oil degradation from mineral oil-based products

     •  Compressor systems with critical gears and bearings

     •  Compressors used in stationary and mobile applications
