Mobil SHC™ Rarus Series

Limit costly downtime by choosing Mobil SHC Rarus Series – synthetic air compressor oils that can meet the demands of today’s severe service conditions.

Our Mobil SHC™ Rarus Series synthetic air compressor oils protect vane and rotary screw air compressors. They are designed for severe service – such as high final compression temperatures or extended oil drain intervals – where other synthetic oils do not meet service life expectations.

Mobil SHC Rarus Series synthetic air compressor oils are formulated to deliver up to three times longer oil drain intervals than other synthetic air compressor lubricants. In fact, Mobil SHC Rarus oils have even demonstrated the ability to perform for up to 24,000 hours in field tests. These oils can also:

  • Minimize need for maintenance and downtime
  • Enhance safety through exceptional durability
  • Support sustainability efforts with extended oil drain intervals
  • Boost productivity while protecting your equipment 

  • maintenance savings

    Minimizes costs and delays of air compressor maintenance

  • oil drop


    Up to 24,000 hours of lubricant life, backed by a three-year warranty*

  • runtime

    Long equipment life due to wear, rust and corrosion protection

  • Outstanding protection, even under extreme service conditions

Supreme Performance Air Compressor Lubricant

Features and Benefits

  • Outstanding thermal / oxidation stability help to provide up to three times oil drain interval versus a leading synthetic compressor oil and reduce maintenance downtime
  • Excellent varnish and sludge control helps to deliver cleanliness and extended compressor oil life
  • High performance synthetic base stocks with high viscosity index enables wide temperature range capability and effective lubrication at high temperatures
  • High load carrying capability protects equipment and extends life, helps minimize unexpected downtime and extend service periods
  • Exceptional resistance to rusting and corrosion, very good antiwear, demulsibility, foam control and air release and multi-metal compatibility
  • Excellent water separability helps reduce carryover to downstream equipment, reduce sludge formation in crankcases and discharge lines, helps reduce blockage of coalescers, coolers and less potential for emulsion formation

 

Applications

  • Mobil SHC Rarus Series are primarily for rotary screw and vane air compressor, very effective in screw type compressors with oil injection cooling; compressors with a history of excess oil degradation, poor valve performance or deposit formation
  • Compressors operating under severe conditions, particularly effective for continuous high temperature operation with discharge temperatures up to 200ºC
  • Compressor systems with critical gears and bearings
  • Not for air compressors used in breathing air applications
  • Compatible with all metals used in compressor construction and with conventional mineral oil-based air compressor oils but mixture with other oils may detract from the total performance capability
