Show original supplier description
The Mobil Rarus 400 Series represents a line of premium performance ashless air compressor lubricants engineered to meet the exacting standards of major compressor manufacturers. This specific formulation offers excellent wear protection and the potential to reduce maintenance costs by minimizing equipment issues and downstream deposits. Its high FZG ratings make it an outstanding lubricant for compressor systems that utilize gears and bearings, positioning it as an excellent selection for both crankcase and cylinder lubrication. Features of the Mobil Rarus 400 Series include low ash and carbon formation, which contributes to improved valve performance and reduced deposits in discharge lines, potentially decreasing the risk of fires and explosions in discharge systems. Its outstanding oxidation and thermal stability promote longer oil life, improved filter performance, and lower overall maintenance costs. The high load-carrying ability helps reduce wear on critical components like rings, cylinders, bearings, and gears. Additionally, excellent water separability minimizes carryover to downstream equipment and reduces sludge formation, while effective rust and corrosion protection enhances the longevity of valves, rings, and cylinders.
