Product Description
The Mobil Rarus™ Excel Series is our improved premium performance ashless air compressor lubricant primarily intended for the lubrication of severe duty rotary screw and vane air compressors. These products are formulated with very high quality mineral base oils and a high performance additive system designed to provide exceptional equipment protection and reliability for compressors operating under severe conditions. Mobil Rarus™ Excel Series provide excellent wear protection and outstanding resistance to oxidation and thermal degradation leading to reduced deposit formation. Mobil Rarus™ Excel Series exceptional water separation characteristics reduce emulsion formation and carryover into downstream piping and equipment.
Features and Benefits
The use of Mobil Rarus™ Excel Series can result in cleaner compressors and lower deposits compared to conventional mineral oils, resulting in longer running periods between maintenance intervals. 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.

Applications
Mobil Rarus™ Excel Series are primarily intended for rotary screw and vane air compressor. Mobil Rarus™ Excel Series are particularly effective in screw type compressors with oil injection cooling and in units with continuous high temperature operation (in line with DIN 51506 indications). The product is compatible with all metals used in compressor construction and with mineral-oil compatible elastomers used in seals, O-rings and gaskets.
Mobil Rarus™ Excel Series are not intended or recommended for use in air compressors for breathing applications.
The following types of compressors have shown excellent performance with Mobil Rarus™ Excel Series:
• Rotary screw compressors
• Rotary vane compressors
• Compressor systems with critical gears and bearings
• Compressors used in stationary and mobile applications
