Compressor oil is a specialized lubricant used in air compressors to reduce friction and wear on moving parts. It helps maintain optimal operating temperatures by dissipating heat generated during the compression process. This oil also prevents rust and corrosion, ensuring the longevity of the compressor. There are different types of compressor oils, including mineral oil and synthetic oil. Mineral oil is derived from refining crude oil, while synthetic oil is chemically engineered for enhanced performance. Choosing the right type of compressor oil is essential for efficient operation and can impact the overall lifespan of the compressor.
