3.The vacuum is high.The ultimate vacuum of Water ring roots unit is 200Pa.The ultimate vacuumof Screw-roots unit can reach 1Pa, which greatly shortens the reaction time;

4.Greatly improve product quality and purity. The water content of the product can be reduced from the original 0.4% to the current 0.0012%;

5.Adapt to the environment and have strong capabilities. Because the summer water temperature high water ring pump can not reach the pre-vacuum demanded by the Roots pump, the water ring Roots unit can not start, andThis situation of Screw-roots unit can be completely avoided;

6.Long lasting. The gas contact parts are coated with Teflon, nickel and Hastelloy to improve the corrosion resistance and wear resistance of the pump;

7.Low noise and low vibration.The two rotors of Screw vacuum pump are subjected to strict dynamic balance correction, and a reasonable gap is left between the two rotors. Therefore, the rotor does not collide when the pump is working, and the operation is stable and the noise is low;

8.Low failure rate and easy maintenance. The design structure is simple, no mechanical seal is used, no frequent failures due to pollution, easy maintenance and repair.
