Airtop DI

Synthetic compressor fluid based on di-ester base stock


Airtop DI series are di-ester based, oxidation resistant lubricant designed to provide high temperature and long-term lubrication with minimal deposits formation. Airtop DI is formulated according to the latest technology and are a combination of high grade synthetic base fluids and specially engineered additive systems. They are used successfully for the long term lubrication of screw, rotary vane and piston type compressors.

Airtop DI offers high performance protection of compressors in extreme conditions: high load and temperatures, compressing reactive and dirty gases, intermittent operation, in warm or cold climates and in mobile applications.


  • Oil flooded rotary screw compressors
  • Oil flooded rotary vane compressors
  • Airtop DI fluids might also be considered for other applications requiring an oxidation resistant lubricant
  • Also recommended for process gas compressors and vacuum pumps
