1.All-in-one, simple installation: integrated oil tank, heat radiator and control panel.
2.Automatic control system provided protection against pump overheat, motor overload and exceeded oil level.
3.Long machine service life. The usage hours of circulating oil is double times more than the other vacuum pumps.
4.Totally sealed pipeline design, clean operation, and without environmental pollution.
5.With built-in high efficient oil mist filters, and the oil mist was filtered out 99.9%.
6.An Inlet vacuum check valve with stainless filter screen prevented the backflow of vacuum oil.
7.The ultimate vacuum of single pump was 3 Torr, and series connected mechanical booster pump reached to 10¯² Torr and pumping speed is increased.
8.A large removable oil sight glasses is easy to check the oil level and clean the circulating oil reservoir.
