What role do vacuum oil filtration systems play in oil purification?

Vacuum oil filtration systems remove contaminants like water, gases, and volatile impurities under vacuum conditions. By reducing the boiling point of these contaminants, they evaporate at lower temperatures without degrading the oil. These systems effectively restore oil’s dielectric strength and lubricating properties. They are essential in applications where moisture removal is critical, such as in transformers and high-performance gear systems.
