The lubricant you choose for your compressor plays a critical role in protecting internal metal parts, preventing corrosion and wear, and sealing; however, requirements vary considerably based on compressor type, the environment in which it is used, and the type of gas that is being compressed.
Lubrication Engineers can help by recommending lubrication reliability best practices – including the right oil – for most compressor types, whether they are centrifugal compressors, reciprocating compressors, rotary screw compressors, rotary vane compressors or dry screw compressors. We have years of documented success helping our customers maximize uptime while reducing costs. When looking for the right oil, it is imperative that a high-quality oil suitable for the application and environment is used.
Qualities of High-Performance Oil for Use in Compressors
- Turbine quality premium oil
- High viscosity index
- High-quality oxidation package exceeding 5,000 hours, per ASTM D943
- Rust and corrosion resistant
- Nonfoaming in use
- Demulsibility properties (ability to shed water)
- Filterable without additive depletion
Once the right oil has been selected – including matching the ISO grade to the OEM spec – the next step is to put the other lubrication reliability pieces in place. Add oil analysis to begin predictive trending of the oil and asset condition, and filtration to keep the oil clean and dry. With these solutions, you can safely extend the life of the asset and the oil – saving time and money.

A strong antioxidant package is essential in a compressor oil. Oil life is reduced by half for every 10°C (18°F) in temperature increase. As oil oxidizes, its viscosity increases, varnish forms, sludge and sediments begin to plug filters, acid increases, and rust and corrosion form. (See photo for progression from new to fully oxidized oil.) All of this is detrimental to the effectiveness and lifespan of the oil and the equipment.
If you are changing oil based on a time interval, you may be getting rid of perfectly good oil and spending money unnecessarily on excess downtime, maintenance and lubricant.
The U.S. Department of Energy states that for an average industrial facility, approximately 10 percent of the electricity consumed is for generating compressed air and can be as high as 30 percent or more of the consumed electricity. Compressed air is one of the most expensive sources of energy in a plant, with the efficiency of a typical compressed air system rated as low as 10 to 15 percent.
Lubrication Engineers can help put together a lubrication reliability program for your compressors to help them last longer, eliminating downtime and reducing maintenance costs.
