Description
Mobil Rarus 827 Supreme performance air compressor lubricant – ISO VG 100
Mobil Rarus 827 is primarily intended for the lubrication of severe duty reciprocating air compressors but not recommended for air compressors used in breathing air applications. It is engineered to meet or exceed the stringent requirements of the major compressor manufacturers. It is formulated with design-specific synthetic base-oils and a high technology additive system that assures exceptional equipment protection and reliability for compressors operating under conditions where mineral-oil based products are not meeting expectations. Rarus 827 provides excellent wear protection and outstanding resistance to oxidation and thermal degradation, greatly superior to mineral oils. Their unique formulation provides the ability to help reduce maintenance costs through minimising equipment problems and downstream deposits and carryover.
Mobil Rarus 827 significantly reduce the potential for fires and explosions, compared to mineral oil-based products. It exhibits a virtual absence of deposit formationand higher autogenous ignition temperatures improving both performance and safety. It’s exceptional water separating characteristics reduce problems with emulsion formation and carryover into downstream piping and equipment. It is recommended or approved by many of the leading compressor manufacturers.
