Mobil SHC Rarus 68

Mobil SHC Rarus ISO VG 68 Synthetic Compressor Oil 

Mobil SHC Rarus 68 (formerly known as: Mobil Rarus SHC 1026) is a supreme performance oil primarily intended for the lubrication of severe duty rotary screw and vane air compressors. It is particularly suited for severe service where mineral oil-based products are not meeting expectations such as in severe applications subjected to high final compression temperatures or where extended oil drain intervals are desired. 

Mobil Rarus SHC 68 is formulated with design-specific wax-free synthetic hydrocarbon fluids and a high technology additive system that assures exceptional resistance to oxidation and thermal degradation far superior to mineral oil-based air compressor oils. It provides outstanding equipment protection and reliability for compressors operating under conditions where other air compressor oils are not meeting expectations. 

It provides excellent wear protection and outstanding resistance to oxidation and thermal degradation, greatly superior to mineral oils. Its unique formulation provides the ability to reduce maintenance costs through minimizing equipment problems and downstream deposits and carryover. This oil's high viscosity index ensures effective lubrication at high temperatures. It also has the following benefits: 

High Performance Synthetic Base Stocks: Wide temperature range capability. Significant performance capabilities relative to mineral oils. Improved safety. Extended service life. Reduced coking deposits. Longer oil life. Improved filter life. Lower maintenance costs. 

High Load-carrying ability: Reduced wear of bearings and gears. 

Excellent Water Separability: Less carryover to downstream equipment. Reduced sludge formation in crankcases and discharge lines. Reduced blockage of coalescers, inter- and after-coolers. Less potential for emulsion formation. 

Effective Rust and Corrosion Protection: Improved protection of internal compressor components 

Application 

• 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
