Compressor Oil

The Witmans line of Compressor Oils has been specifically formulated from highly refined paraffinic base oils and high quality additives for the lubrication of rotary and reciprocating air compressors.


There are eight grades of Witmans Compressor Oil available- 32, 46, 68, 100, 150, 220, 320, and 460. Compressor oils 32, 46, and 68 are developed specially for rotary vane and screw compressors. Compressor oils 68, 100, 150, 220, 320, and 460 are effective as once-through lubricants for reciprocating compressor cylinders, crankcases, and some rotary compressors.

Each grade of compressor oil, when used within its recommended application temperature and viscosity range, will offer the following features and benefits:

  • Excellent lubrication of cylinder, piston ring, and timing gears and bearings in
  • rotary compressors
  • High compressor efficiency
  • Enhanced oil life in circulating systems and crankcases
  • Optimum corrosion and wear protection
  • Excellent water separation aids in draining excess moisture
  • Reduced sight glass staining of compressors equipped with automatic lubricators
  • Excellent air/oil separation when used in flood-lubricated rotary compressors

  • Foam protection- Grades 32 through 220 contain an effective foam inhibitor

‘Witcol Circulating Grades’ meet the requirements of IS: 10522-1983 specifications.
