How does a lube oil purifier work?

A lube oil purifier works by removing contaminants from used lubricating oil to restore its quality. The process typically involves three main stages: separation, filtration, and dehydration. In the separation stage, the oil is subjected to centrifugal force to separate particles, water, and other impurities based on density differences. The filtered oil is then dehydrated to remove any remaining moisture, resulting in cleaner, reusable lube oil.
