Rarus® 427 Air Compressor Oil

Features

Applications

·Rrecommended for single and multistage air compressors.
·Effective for continuous high temperature operation.
·Maximum compressed air temperature, according to DIN 51506, is 220°C.
·Suitable for reciprocating and rotary type machines with the lower viscosity grades mainly used in rotary compressors.
·Recommended for units with a history of excess oil degradation, poor valve performance or deposit formation.
·Compatible with all metals used in compressor construction and with mineral-oil compatible elastomers used in seals, O-rings and gaskets.
*Not intended or recommended for use in air compressors for breathing applications. The following types of compressors have shown excellent performance with the Mobil Rarus 400 Series oils:
·Reciprocating air compressor crankcases and cylinders.
·Rotary screw compressors.
·Rotary vane compressors.
·Axial and centrifugal compressors.
·Compressor systems with critical gears and bearings.
·Compressors used in stationary and mobile applications.

Benefits

·Cleaner compressors and lower deposits compared to conventional mineral oils, resulting in longer running periods between maintenance intervals.
·Excellent oxidation and thermal stability safely allow extended life capability while controlling sludge and deposit formation.
·Possess outstanding anti-wear and corrosion protection, which enhances equipment life and performance.
·Improved valve performance.
·Reduced deposits in discharge lines.
·Reduced potential for fires and explosions in discharge systems.
·Improved compressor performance.
·Longer oil life.
·Improved filter life.
·Lower maintenance costs.
·Reduced wear of rings, cylinders, bearings and gears.
·Less carryover to downstream equipment.
·Reduced sludge formation in crankcases and discharge lines.
·Reduced blockage of coalescers.
·Less potential for emulsion formation.
