Choosing the Right Oil for Industrial Air Compressors: A Comprehensive Guide

Factors like oil types, viscosity, environmental conditions, regulations, and maintenance underscore the significance of proper oil selection for prolonged equipment life and cost-effectiveness.

Industrial air compressors are indispensable in numerous applications, energizing pneumatic tools and machinery across industries. Optimal performance, longevity, and energy efficiency of these machines rely on the selection of the appropriate oil. With countless options available, like Summit brand oils known for their high quality, selecting the right product for your industrial air compressor can seem daunting. In this guide, we’ll simplify the process, diving into crucial factors in oil selection and offering insights to assist your decision.

Understanding the Role of Compressor Oil

Compressor oil has many responsibilities in industrial air compressors. It lubricates moving parts and prevents premature wear. In rotary screw compressors, the compressor oil also acts as a coolant that helps cool the compressor and discharge air during compression. 

Types of Compressor Oil

There are various compressor oils available, each boasting its unique properties and suitable applications. They are primarily classified into mineral-based oils and synthetic oils, such as those carefully engineered by the experts at Summit Lubrication.


  1. Mineral-based oils: Refined petroleum-derived oils that provide decent lubrication properties at a reasonable cost. They are suitable for non-demanding applications under standard operating conditions.

  2. Synthetic oils: Summit synthetic compressor oils are designed for high performance, particularly under demanding conditions. They provide enhanced lubrication, superior oxidation resistance, and improved viscosity at high temperatures, making them an excellent choice for heavy-duty compressors and applications requiring longer oil change intervals.

Viscosity and Compatibility

Viscosity, indicative of a fluid’s resistance to flow, is a pivotal factor when selecting compressor oil. It influences the oil’s lubrication efficiency under different operating conditions. Compressor manufacturers, including those of new models, typically suggest a specific viscosity range based on temperature, pressure, and compressor type. Choosing an oil with the correct viscosity ensures optimal lubrication and prevents excessive wear or inadequate lubrication. It is important to note that for all new compressors, OEM-recommended oil should be used to maintain warranties. Using non-OEM oils can void these warranties. 

Environmental Factors and Regulations

Take into account the environment your industrial air compressor operates in. Factors such as temperature, humidity, and airborne contaminants can affect the performance and longevity of the compressor oil. For instance, if your compressor operates in extremely high temperatures, selecting an oil with excellent thermal stability and resistance to oxidation is crucial. Furthermore, be mindful of any regulatory requirements or environmental standards that apply to your industry to ensure a safe working environment and prevent potential legal issues. Industries like Food & Beverage have strict regulations on what oils can and cannot be used in the operation.

Maintenance and Monitoring

Regular maintenance and oil sampling are critical for the long-term and efficient operation of industrial air compressors. Consider the availability of oil sampling services. Investing in oil sampling can provide valuable insights into the oil’s condition, enabling proactive measures before significant damage occurs. On-site acid testing is also available, giving you instant insight on the acidity of your compressor’s oil.

Choosing the right oil for your industrial air compressor is paramount for its performance, longevity, and energy efficiency. Consider factors such as the role of compressor oil, types of oils available, viscosity, compatibility, environmental factors, regulations, and maintenance requirements to make an informed decision. While brands like Summit Lubrication offer superior performance, remember to use OEM-specified oil for new compressors to maintain warranties. By selecting the right oil, you can ensure smooth operation, reduce maintenance costs, and extend the lifespan of your industrial air compressor. Always prioritize quality, compatibility, and regulatory adherence to maximize the efficiency and reliability of your equipment.
