Description:

Mobil Rarus 400 Series air compressor lubricants are made from solvent refined high quality paraffinic stock oils having carefully controlled properties. They incorporate novel additive technology to give outstanding antiwear, anti-rust and anti-oxidant performance. Mobil Rarus 424, 425 and 426 include ‘keep clean’ properties which are particularly important in rotary compressors.

They are available in five viscosity grades, and are branded Mobil Rarus 424, 425, 426, 427 and 429.

Mobil Rarus 400 Series lubricants exceed DIN-51506 VDL requirements. 

Benefits:

Mobil Rarus 400 Series products offer the following benefits:

• Vastly increased oil life - extensive rig and field test results have shown over double the life can be obtained, particularly in rotary compressors, compared with conventional products
• Excellent protection against oil separator clogging in rotary compressors
• Exceptional resistance to oxidation and deposit formation, gives longer valve cleaning intervals
• Reduced ring and cylinder wear due to good rust protection and load carrying characteristics
• Reduced oil consumption and carry over due to excellent product stability
• Lower maintenance costs, reduced downtime - increased operating profits 

Applications:

Mobil Rarus 400 Series lubricants are recommended for single and multi-stage air compressors, and are particularly effective for continuous high temperature arduous operation with exhaust temperatures up to 220°C. They are suitable for both reciprocating and rotary type machines, although the lower viscosity grades will mainly see operation in rotary compressors.

They are recommended and/or approved by all major air compressor manufacturers in UK and Europe.

Mobil Rarus 400 Series lubricants are also suitable for crankcase lubrication in crosshead type reciprocating machines.
