Compressor Lubricants

Compressor lubricants are critical to efficient operation

Most factories and manufacturing facilities use compressed gas systems for a variety of applications, and keeping these air compressors running is critical to keeping the entire operation running. Nearly all compressors require a form of lubricant to cool, seal or lubricate internal components. Proper lubrication will ensure that your equipment will continue operating, and the plant will avoid costly downtime and repairs. Proper lubrication also will help compressors run cooler and consume less electrical energy. It is simple: reduced friction = reduced heat = reduced energy consumption. Compressed air systems in most manufacturing plants consume a majority of the daily power requirements, so if you are looking for a continuous improvement project, reducing energy costs through better lubricant practices is a sure winner.

Choose the right compressor lubricant

Lubrication requirements vary considerably based on compressor type, the environment in which it is used, and the type of gas that is being compressed. Lubricant plays a critical role in sealing, preventing corrosion, preventing wear, and protecting internal metal parts. LE has the right lubricants for most compressor types, whether they are centrifugal compressors, reciprocating compressors, rotary screw compressors, rotary vane compressors or dry screw compressors.

When looking for an air compressor lubricant, first look at the viscosity requirements. After the viscosity requirements are identified, look for a lubricant that provides the following benefits.

  • Excellent rust and corrosion protection
  • High oxidation stability to maintain its viscosity and provide long service life
  • Nonfoaming
  • Demulsibility properties to shed water
  • Filterability without the worry of lubricant additive depletion

Don’t shoot for the bottom of the barrel when it comes to operating specifications. Instead, look for lubricants that exceed specifications. In doing so, you will help your air compressor equipment last longer and run more efficiently.




Monolec®

Look for products that contain Monolec

Monolec, LE’s in-house wear-reducing additive, creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances, and allowing for opposing surfaces to slide by another. The result is greatly reduced friction, heat and wear. Learn more about Monolec.
