Manufacturer's description
The Mobil Rarus 800 Series is a line of supreme performance air compressor lubricants primarily intended for severe-duty reciprocating air compressors, though not recommended for breathing-air applications. Engineered to meet or exceed the requirements of major compressor manufacturers, they are formulated with design-specific synthetic base oils and a high-technology additive system that assures exceptional equipment protection where mineral-oil products fall short, providing excellent wear protection and oxidation and thermal stability far superior to mineral oils. The series significantly reduces the potential for fires and explosions compared to mineral oil-based products, thanks to a virtual absence of deposit formation and higher autogenous ignition temperatures, while exceptional water-separating characteristics reduce emulsion problems and carryover into downstream equipment. It is recommended for single- and multistage air compressors for continuous high-temperature operation with discharge temperatures up to 200°C, suitable for reciprocating and rotary machines, cylinder and crankcase lubrication, and compressor systems with critical gears and bearings, in stationary and mobile applications, and is compatible with common seal materials such as Viton, Teflon, and high-nitrile Buna N. The Mobil Rarus 800 Series meets or exceeds China GB/T 12691-2021 L-DAB requirements and is recommended or approved by many leading compressor manufacturers. It is available in three ISO viscosity grades: Rarus 824 (ISO 32), 827 (ISO 100) and 829 (ISO 150), with viscosity indices from 66 to 127, flash points from 244°C to 270°C, and pour points as low as -54°C.
Applications
- The Mobil Rarus 800 Series oils are recommended for single and multistage air compressors, but are not recommended for air compressors used in breathing air applications. They are particularly effective for continuous high temperature operation with discharge temperatures up to 200ºC. They are suitable for reciprocating and rotary type machines with the lower viscosity grades mainly used in rotary compressors. Rarus 800 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-based lubricants but admixture will detract from their performance capabilities. Mobil Rarus 800 Series oils are compatible with seals made from fluorinated hydrocarbon, silicone, fluorosilicone, polysulfide, Viton, Teflon, and high nitrile Buna N NBR (above 36% acrylonitrile) materials. Materials not recommended include low nitrile Bune N NBR (below 30% acrylonitrile), natural and butyl rubbers, Neoprene, polyacrylate, styrene/butadiene and chlorosulfonated polyethylene. Oil resistant paints are not affected by Mobil Rarus 800 Series, but lacquer, varnish, pvc and acrylic paints are not recommended. The following types of compressor applications have shown excellent performance with the Mobil Rarus 800 Series oils: • All types of air compressors but specifically recommended for reciprocating air compressor • Units operating under severe conditions • Multistage units with a history of excessive oil degradation from mineral oil-based products • They can be used for cylinder and crankcase lubrication • Compressor systems with critical gears and bearings • Compressors used in stationary and mobile applications
