Vacuum pumping unit is mainly used for pumping the gas from container to ensure the container could meet with high vacuum requirements. At the same time, it is also useful for vacuum drying. This unit is particularly suited to the power industry transformer vacuum operation. It can be used for vacuum metallurgy, welding, chemical and pharmaceutical, vacuum coating, electronic components and other industries. The host can adopt original German Leybold Air-cooled Style Vane Rotary vacuum pump and roots booster, it can be designed according to customer request, too. It has fast startup, quick pumping, stable performance, and simple operation features and so on.


1. With quick start, high pumping speed, stable performance, easy operation, etc.

2. The roots pump as the main pump, rotary vane vacuum pumps as backing pump.

3. Fully automatic operation, but no one to operate, running state by the indicator light display.

4. Humanized design, low noise, low energy consumption to save running costs.

5. Equipped with pipeline filter can effectively prevent the larger particles of impurities into the system, damage the vacuum pump

6. Equipped with pneumatic non-return device, can prevent abnormal gas circumfluence, vacuum leak , run oil  phenomenon,etc.

7. Use imported pumps, and can obtain higher work vacuum degree quickly.
