The transformer oil filter is mainly divided into two categories: ordinary vacuum oil filter and two stage high efficiency vacuum oil filter.

The transformer oil filter oil can quickly remove the harmful components in the liquid, such as water, gas and impurities in the transformer oil, improve the lubricating performance of the transformer oil, reduce the corrosion or corrosion of the transformer oil to the oil equipment because of the heavy moisture or impurity content, and prolong the service life of the oil equipment.

Transformer oil filter is a kind of mechanical equipment for filtering solid impurities and moisture in oil, improving oil quality and improving insulation strength of transformer oil. It is used in power plant, power plant, electric power company, metallurgy, petrochemical, railway and other industrial and mining enterprises to purify the special equipment for unqualified electrical insulating oil. It can also vacuum the insulated power equipment and vacuum dry electric equipment.
