Air Compressor Lubricants

Mobil Rarus 400 Series
Air Compressor Lubricants
Product Description
The Mobil Rarus 400 Series is a line of premium performance ashless air compressor lubricants designed to
meet the stringent requirements of the major compressor manufacturers. They are formulated with high quality
mineral base-oils and a high performance additive system designed to provide exceptional equipment protection
and reliability for compressors operating under mild to severe conditions. They provide excellent wear protection
and the ability to reduce maintenance costs through minimising equipment problems and downstream deposits
and carryover. Because of their high FZG Ratings, the Mobil Rarus 400 Series make outstanding lubricants for
compressor systems employing gears and bearings making them an excellent selection for crankcases as well
as cylinder lubricants. Mobil Rarus 400 Series lubricants exceed the requirements of DIN 51506 VD-L standards
and demonstrate a very high resistance to oxidation and deposit formation. They are recommended or approved
by many of the leading compressor manufacturers.
Features and Benefits
The use of the Mobil Rarus 400 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.
