Industrial air compressors are heavy-duty equipment that can last up to 30 years when given proper maintenance. One part of their care includes choosing the right lubricants to minimize friction between the motor's components. The wrong type results in excessive energy consumption and reduces the compressor's operational lifespan. The following guide explores what you need to know about selecting lubricants to keep your air compressor in top condition for the long term. 

Standard Vs. Synthetic

Though there are many lubricants to choose from, they fall into two main categories—standard and synthetic. Each has unique features that benefit specific air compressors. The standard version typically has a mineral oil base and is ideal for compressors that provide light- or medium-duty performance. 

Synthetic lubricants go through more processing, resulting in a refined product. Compressors used frequently, such as at least three times a week, benefit from a synthetic since the fluid prevents overheating and premature wear of the motor and components.

How Often to Change Lubricants

The air compressor owner's manual is the best guide for determining how often to replace old lubricants for specific models. In general, the type of compressor dictates the schedule for changing lubricants. For example, reciprocating types may need new fluid every three months, while rotary screw-type compressors could require a fresh supply every 7,000–8,000 hours of use. At the very least, lubricant should be changed annually to reduce the chance of premature motor wear and overheating.

Recommissioning Care

Sometimes owners mistakenly believe that older compressors sitting idle for years should simply be recommissioned. However, technicians highly recommend that these compressors undergo thorough flushing to remove all old lubricants before recommissioning. This is because mixing the wrong types could result in a foaming or thick molasses reaction that can corrode components. Since choosing the correct lubricant is crucial for protecting the compressor from damage, Varnasolv^® is an ideal cleaning solution for this vital pre-treatment step.
