1. The vacuum seperation of the purifier employs a particular stainless, foldable column for dehydration and degassing, and enlarges the area of oil separation to facilitate three-dimensional evaporation, so as to achieve the best effect of separation.

2. It uses a new-type heating equipment, which has a low heating load and is able to prevent oil from ageing.

3. It uses an imported liquid ring vacuum pump and takes cooling liquid(or water) as a lubricating medium.

4. Its oil level control adopts a photoelectric mode and features a very sensitive and precise control. Even foams can be sensed.

5. It uses a special high-viscosity oil feed pump and adopts a special sealing treatment. It is free from oil leakage, low operational noise and long useful life.

6. China-made filtering elements can be inter-replaced with Italy-imported ones so users can resort to a suitable filtering material according to the quality of different oil.
