Transformer Oil Filter Machine

Leading manufacturer and supplier of transformer oil filter machines for oil purification, dehydration, degassing, and BDV improvement applications.

Our Transformer Oil Filter Machine is a high-performance vacuum oil filtration and purification system designed to remove moisture, dissolved gases, sludge, carbon particles, and impurities from transformer insulating oil. The machine restores the oil’s dielectric strength (BDV) and improves the overall performance, safety, and life of power transformers.

Using advanced vacuum dehydration, degassing, and multi-stage fine filtration technology, the system ensures efficient purification of transformer oil for both new transformer oil filling and used oil reclamation during maintenance.

This machine is widely used by transformer manufacturers, power utilities, electrical maintenance contractors, service providers, and industrial plants for the filtration of oil in power transformers, distribution transformers, OLTC compartments, reactors, and other oil-filled electrical equipment.
