Oil filters use vacuum dehydration, heating, and fine filtration to remove water, gases, acids, and particles. Vacuum lowers boiling point to extract moisture and dissolved gases. Filters trap solid contaminants. Some systems include adsorption media to reduce acidity. Clean oil restores dielectric strength and improves cooling performance.
