Mobil Rarus™ 827 Series - Air Compressor Lubricant (208LT)

Mobil Rarus™ 800 Series - Supreme Performance Air Compressor Lubricants

>>Download Datasheet<<

The Mobil Rarus™ 800 Series is a line of supreme performance air compressor lubricants primarily intended for the lubrication of severe-duty reciprocating air compressors, though they are not recommended for breathing air applications. Engineered to meet or exceed the stringent requirements of major compressor manufacturers, these lubricants are formulated with advanced synthetic base-oils and a high-technology additive system that ensures exceptional equipment protection and reliability.

They are particularly effective for continuous high-temperature operation with discharge temperatures up to 200ºC. Their excellent wear protection and outstanding resistance to oxidation and thermal degradation are greatly superior to mineral oils. The unique formulation helps to reduce maintenance costs by minimizing equipment problems and downstream deposits and carryover.

Mobil Rarus 800 Series lubricants significantly reduce the potential for fires and explosions compared to mineral oil-based products, exhibiting a virtual absence of deposit formation and higher autogenous ignition temperatures. Their exceptional water-separating characteristics reduce problems with emulsion formation and carryover into downstream piping and equipment.

Features and Benefits

• Extended Service Life: Provides cleaner compressors and lower deposits compared to conventional mineral oils, leading to longer intervals between maintenance.

• Superior Thermal and Oxidation Stability: Safely allows for extended life capability while controlling sludge and deposit formation.

• Enhanced Equipment Protection: Outstanding anti-wear and corrosion protection enhances equipment life and performance.

• Improved Safety: Significantly reduces the risk of fires and explosions due to minimal deposit formation and a higher autogenous ignition temperature.

• Versatile Application: Suitable for both reciprocating and rotary type machines, with lower viscosity grades primarily used in rotary compressors.

• Problem-Solving Formula: Recommended for units with a history of excess oil degradation, poor valve performance, or deposit formation.

Recommended Applications

The Mobil Rarus 800 Series oils have demonstrated excellent performance in a range of compressor applications, including:

• All types of air compressors, with a specific recommendation for reciprocating air compressors.

• Units operating under severe conditions.

• Multistage units with a history of excessive oil degradation from mineral oil-based products.

• Can be used for cylinder and crankcase lubrication.

• Compressor systems with critical gears and bearings.

• Compressors used in stationary and mobile applications.

Compatibility

• Metals: Compatible with all metals used in compressor construction.

• Lubricants: Compatible with mineral oil-based lubricants, but admixture will detract from performance.

• Seals: 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 Buna N NBR (below 30% acrylonitrile), natural and butyl rubbers, Neoprene, polyacrylate, styrene/butadiene, and chlorosulfonated polyethylene.

• Paints: Oil-resistant paints are not affected, but lacquer, varnish, PVC, and acrylic paints are not recommended.
