EV series compound molecular pumps

Short Description:

EV-series compound molecular pumps are composed of turbo molecular pumps and disk traction pumps. They have the characteristics of high pumping speed, high compression ratio, high pumping speed and high compression ratio at high pressure, and expand the application scope of molecular pumps.The compound molecular pump has no selectivity and memory effect on the pumped gas. Because of its high compression ratio to the gas with large molecular weight, the pump can obtain clean high and ultra high vacuum without cold trap and oil baffle. It is widely used in various fields of electronics, metallurgy, chemical industry, scientific research and vacuum technology.

EV Series Air-cooling compound Molecular Pumps

EV-series air-cooled compound molecular pump is composed of turbomolecular pump and disc traction pump. It has the characteristics of high pumping speed and compression ratio for molecular flow of turbomolecular pump, high pumping speed and compression ratio for high pressure of traction pump, and expands the application scope of molecular pump.
The compound molecular pump has no selectivity and memory effect on the pumped gas. Because of its high compression ratio to the gas with large molecular weight, the pump can obtain clean high and ultra high vacuum without cold trap and oil baffle.
