Features and Benefits
The use of the Mobil Rarus SHC 1020 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.
| Features | Advantages and Potential Benefits |
| High Performance Synthetic Base Stocks | Wide temperature range capability Significant performance capabilities relative to mineral oils Improved safety Extended service life |
| Outstanding Oxidation and Thermal Stability | 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 |
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
