• Pack size:  20 l canister
• Also available in: 208 l drum

Applications 

• For single and multistage air compressors. They are particularly effective for continuous high temperature operation. The 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.
• Rarus 400 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 mineral-oil compatible elastomers used in seals, O-rings and gaskets.
• 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
