1. Double stage high vacuum pumping system: except the rotary vane vacuum pump, this machine is also equipped with a root vacuum pump, so it has faster vacuum-pumping speed and can reach a very good ultimate vacuum.

2. Equipped with JUNSUN specially designed and unique “Horizontal - Vertical Combined Vacuum Tank”, together with advanced degasification and dehydration technology, which can remove gas and water very quickly and effectively.

3. Equipped with high precision three stage oil filtration system, including Primary Filter, Fine Filter 1 and Fine Filter 2, which have gradually increasing precision, the dimensions of filter element are bigger than most of other manufacturers, which can effectively remove mechanical impurities from oil.

4. Equipped with automatic temperature control system, automatic oil level control system, automatic defoaming control system, automatic pressure protection system, which guarantees safe and reliable operation in the long term.

5. Equipped with comprehensive protection mechanism, such as power protection, pressure protection, motor overload protection. If any protection mechanism is triggered, the machine will stop working automatically.

6. Equipped with high efficiency electric heating system, heating the oil uniformly, avoid the deterioration of oil during heating process.

7. This machine is able to operate offline or online at indoor or outdoor. In addition, this machine has a specialized vacuum pumping interface, if equipped with related optional features, it can be also used as independent vacuum pump set to pull vacuum for transformers.
