What are the specifications of transformer oil filtration machines?

Transformer oil filtration machines typically have specifications that include a flow rate ranging from 100 to 3000 liters per hour, a filtration accuracy of 1 to 5 microns, and the ability to remove water content down to 10 parts per million (ppm). They often feature multi-stage filtration systems, vacuum dehydration capabilities, and automatic control systems for monitoring temperature and pressure. Additionally, they may include a built-in heater to facilitate the removal of moisture from the oil.
