If a machine has rust issues in the operating or connecting parts, or if the connections are too tight with obstructions, it will reduce work efficiency during operation. Compressor oil is used in many factories for lubricating compressors, and its principle is to reduce friction between parts, as well as to clean off residues between the two friction surfaces. Keeping the machine parts well-lubricated during operation will improve work efficiency.

Air compressor oil not only reduces friction between two surfaces but also provides lubrication for the machine's components, serving as a form of protection. To maintain optimal working efficiency, machines cannot do without the nourishment of lubricating oil. However, allowing the machine to rest reasonably is also a way to enhance its efficiency.

Lubricants designed for various machines are the lifeblood of their operation. Transformer oil, specifically used in transformers or circuit breakers, is extracted from crude oil and then refined into a lubricant suitable for machinery. It provides excellent safety protection for electrical equipment such as transformers.
