Edwards nEXT85 Compound Turbomolecular Vacuum Pump - NEW
The nEXT85 turbomolecular pump builds upon the success of the highly successful 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.
