5 Types Of Compressor Oil

Compressor oil acts as a lubricant, protecting the internal components of the compressor from wear and tear, and ensuring smooth operation. However, not all compressor oils are a good choice. There are different types of compressor oils available on the market, each with its unique properties and purpose.

In this article, we will discuss five common types of compressor oil used in various air compression systems.

Mineral oil

Mineral oil is the most commonly used type of compressor oil. It is made from refined petroleum and offers a balance of performance and affordability. Mineral oils are suitable for standard compressors operating under normal conditions and offer good lubrication, oxidation resistance, and cooling properties. However, mineral oils may not be ideal for high-temperature or extreme-duty applications, where synthetic oils are often preferred.

Synthetic oil

Synthetic compressor oils are engineered to provide superior performance compared to mineral oils. These oils are manufactured using synthetic processes, which result in a more stable molecular structure. Synthetic oils are particularly beneficial for compressors operating under high temperatures, heavy loads, or extreme conditions. They offer improved oxidation stability, reduced wear, and better flow at lower temperatures, making them ideal for more demanding applications.

Semi-synthetic oil

Semi-synthetic oils are a blend of mineral oil and synthetic oil, offering a balance between cost-effectiveness and performance. These oils are designed to provide improved protection and lubrication while maintaining the affordability of mineral oils. Semi-synthetic oils are suitable for compressors that operate under moderate conditions or for businesses that need a compromise between performance and cost.

Polyalphaolefin (PAO) oil

Polyalphaolefin oil is a type of synthetic oil commonly used in high-performance compressor applications. PAO oils provide excellent stability and resistance to heat and oxidation, making them ideal for compressors that operate in harsh conditions. PAO oils offer lower volatility, reducing the risk of oil evaporation, and they provide superior lubrication in high-load applications.

Ester oil

Ester-based compressor oils are made from organic acids and alcohols. They are known for their high lubricity and ability to work in extreme temperature conditions. Ester oils are commonly used in rotary screw compressors and other high-performance equipment where high levels of lubrication are needed. They also have good biodegradability, making them an environmentally friendly option.
