Feature and Potential Benefits
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.
| Features | Advantages and potential benefits |
|---|---|
| Low Ash and Carbon Formation | Improved valve performance, Reduced deposits in discharge lines, Reduced potential for fires and explosions in discharge systems, Improved compressor performance |
| Outstanding Oxidation and Thermal Stability | Longer oil life |
| Improved filter life, Lower maintenance costs | |
| High Load-carrying ability | Reduced wear of rings, cylinders, bearings and gears |
| Excellent Water Separability | Less carryover to downstream equipment, Reduced sludge formation in crankcases and discharge lines, Reduced blockage of coalescers, Less potential for emulsion formation |
| Effective Rust and Corrosion Protection | Improved protection of valves and reduced wear of rings and cylinders |
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
