High Negative Pressure Three Lobe Roots Vacuum Pump
1) When running, the ultimate vacuum is as high as 50%.
2) The theoretical displacement range is 1000-10500m3/h.
3) It can be used to transport industrial gases and steam.
4) No sliding friction parts, reducing wear.
5) Environmental protection and safe operation
6)No oil mist in the exhaust.
7)It can meet ATEX standard explosion-proof requirements.
