Mobil Rarus 829 Air Compressor Lubricant 5 Gal / 18.9 L canister

Mobil Rarus 829 Supreme performance air compressor lubricant - ISO VG 150 ( 151711, 101131 )

Mobil Rarus 829 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 829 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 829 significantly reduce the potential for fires and explosions, compared to mineral oil-based products. It exhibits a virtual  absence of deposit formation and 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.

The Mobil Rarus™ 800 series is also available in ISO VG 32 (Mobil Rarus 824) and 100 (Mobil Rarus 827)
