Energol RC-R 68

Air compressor lubricant

The Energol RC-R™ compressor oil range of lubricants are based upon highly refined mineral oils and carefully chosen additives. They are intended for the lubrication of rotary and reciprocating compressors.

The Energol RC-R grades are ash less oils recommended for the lubrication of rotors, bearings and gears in rotary compressors, especially the oil flooded screw type. Energol RC-R can be used for either normal or severe duty lubrication of reciprocating and rotary drip-feed air compressors, as defined by ISO 6743. Energol RC-R compressor oils exhibit low carbon forming tendencies and meet the requirements of the DIN 51506 VDL classification for reciprocating compressors having air discharge temperatures up to 220°C. Selection of the required viscosity grade should be based upon the compressor manufacturers’ recommendation however as a general guide Energol RC-R 32 and 46 are suitable for oil flooded rotary compressors, whereas Energol RC-R 68 and 100 would be selected for lubricating the crankcase and cylinders of reciprocating compressors.

Energol RC-R 150 is recommended for sliding-vane compressors, or for reciprocating units at high ambient temperatures. The Energol RC-R range is fully compatible with nitrile, silicone and fluoropolymer seal materials.

Energol RC-R grades are classified as follows:

  • DIN 51506 classification – VDL
  • ISO 6743/4 – DAA and DAB for reciprocating air compressors, DAG for rotary air compressors.
  • Good water separation characteristics allow condensation residues to readily separate from the oil, minimizing the risk of emulsions which could block the oil separator element.
  • Prevents corrosion when operating under humid conditions.
  • Excellent coalescing properties mean minimal carry over of oil in the air stream.
  • Low deposit forming tendencies extends oil change intervals and provides longer air filter life which contributes to a reduction in maintenance costs.
  • Good thermal stability, low volatility and low carbon formation reduces the risk of fire and explosion.
