Mobil Rarus SHC 1000 Series
Air Compressor Lubricant
Product Description
The Mobil Rarus SHC 1000 Series is a line of supreme performance oils primarily intended for the lubrication
of severe duty rotary screw and vane air compressors. They are particularly suited for severe service where
mineral oil-based products are not meeting expectations such as in severe applications subjected to high final
compression temperatures or where extended oil drain intervals are desired. They are formulated with
design-specific wax-free synthetic hydrocarbon fluids and a high technology additive system that assures
exceptional resistance to oxidation and thermal degradation far superior to mineral oil-based air compressor
oils. They provide outstanding equipment protection and reliability for compressors operating under conditions
where other air compressor oils are not meeting expectations. Mobil Rarus SHC 1000 Series provide excellent
wear protection and outstanding resistance to oxidation and thermal degradation, greatly superior to mineral
oils. Their unique formulation provides the ability to reduce maintenance costs through minimising equipment
problems and downstream deposits and carryover. Their high viscosity index ensures effective lubrication at
high temperatures.
Mobil Rarus SHC 1000 Series lubricants significantly reduce the potential for fires and explosions when compared
to mineral oil-based products. They exhibit a virtual absence of deposit formation and high autogeneous ignition
temperatures improving both performance and safety. Their exceptional water separating characteristics reduce
emulsion formation problems which may lead to blockage of coalescers and filters, thus reducing the need for
frequent maintenance.
Features and Benefits
The use of the Mobil Rarus SHC 1000 Series oils can result in cleaner compressors and lower deposits compared
to conventional mineral oils, resulting in longer running periods between maintenance intervals. Their excellent
oxidation and thermal stability safely allow extended life capability while controlling sludge and deposit formation.
They possess outstanding anti-wear and corrosion protection, which enhances equipment life and performance.

Applications
The Mobil Rarus SHC 1000 Series oils are primarily intended for rotary screw and vane compressors. They are
particularly effective for continuous high temperature operation with discharge temperatures up to 200º . Rarus
SHC 1000 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 conventional
mineral oil-based air compressor oils but admixture with other oils may detract from the total performance
capability.
Mobil Rarus SHC 1000 Series oils are not recommended for air compressors used in breathing air applications.
The following types of compressor applications have shown excellent performance with the Mobil Rarus SHC
1000 Series oils:
• Primarily recommended for rotary screw and vane air compressor
• 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
