nEXT85 Turbomolecular Pumps

Edwards, a world leader in vacuum technology, is proud to present the nEXT generation of turbomolecular pumps. The nEXT85 turbomolecular pump builds upon the success of the EXT75DX to deliver a pump with significantly improved performance in a smaller package. The rotor has been totally re-designed to optimise pump performance and achieve both higher speeds and higher compression while maintaining high levels of reliability. In addition to enhanced performance, nEXT85 benefits from the same service and operational functionalities from the larger nEXT range, including field serviceability and in-built intelligence, for a truly class leading product.

Features and Benefits
  • Class leading performance in a reduced footprint
  • Enhanced customer choice with standard and compression focused variants
  • Increased operating envelope maximised by Edwards’ patented direct impeller temperature measurement technology
  • Additional flexibility from customised interstage and backing port position selection
  • The bearing and oil cartridge in the nEXT85 are fully end-user serviceable
  • CMSD enabled low vibration levels
  • Intelligent pumps with included micro USB port and Edwards nST software allowing pump monitoring, control and configuration
  • Full suite of tailored accessories
Applications:
  • Mass spectrometry
  • Electron microscopy
  • Research and development
  • High energy physics
  • Industrial
