Manufacturer's description

The Mobil Rarus SHC 1020 Series is a line of supreme performance oils primarily intended for the lubrication of severe-duty rotary screw and vane air compressors, particularly suited to severe service such as high final compression temperatures or where extended oil drain intervals are desired. Formulated with design-specific wax-free synthetic hydrocarbon fluids and a high-technology additive system, they offer resistance to oxidation and thermal degradation far superior to mineral oil-based air compressor oils, along with a high viscosity index for effective lubrication at high temperatures. The series significantly reduces the potential for fires and explosions compared to mineral oil-based products, showing a virtual absence of deposit formation and high autogenous ignition temperatures, plus exceptional water-separating characteristics that reduce emulsion problems in coalescers and filters. It is primarily recommended for rotary screw and vane compressors, especially screw-type units with oil-injection cooling, effective for continuous high-temperature operation up to 200°C discharge temperature; it is compatible with all metals used in compressor construction and with conventional mineral oils, though admixture may reduce overall performance, and it is not recommended for breathing-air compressors or discharge temperatures above the product's flash point. The Mobil Rarus SHC 1020 Series meets or exceeds China GB/T 12691-2021 L-DAJ requirements. This product is Mobil Rarus SHC 1024, ISO viscosity grade 32, with a kinematic viscosity of 31.5 mm²/s at 40°C and 5.7 mm²/s at 100°C, a viscosity index of 127, a flash point of 245°C and a pour point of -48°C. The other grades in the series are Rarus SHC 1025 (ISO 46) and Rarus SHC 1026 (ISO 68).

Applications

• Primarily rotary screw and vane compressors, particularly effective for continuous high-temperature operation, with discharge temperatures up to 200°C.
• Units with a history of excess oil degradation, poor valve performance or deposit formation.
• Compatible with all metals used in compressor construction and with conventional mineral-oil-based air-compressor oils, although admixture with other oils may detract from overall performance.
• Not recommended for air compressors used in breathing-air applications, and should not be used where the discharge temperature exceeds the product's flash point.
• Primarily recommended for rotary screw and vane air compressors, 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.

Performance & benefits

• Cleaner compressors and lower deposits compared with conventional mineral oils result in longer running periods between maintenance intervals, thanks to excellent oxidation and thermal stability that safely allow extended service life while controlling sludge and deposit formation, along with outstanding anti-wear and corrosion protection that enhances equipment life and performance.
• High load-carrying ability and excellent water separability reduce wear of bearings and gears, reduce carryover to downstream equipment, reduce sludge formation in crankcases and discharge lines, reduce blockage of coalescers and inter-/after-coolers, and lower the potential for emulsion formation.
• Effective rust and corrosion protection improves protection of internal compressor components.
