nEXT400D ISO-K160 160W

nEXT Turbomolecular pumps are hybrid bearing pumps with a compound drag stage and integrated controllers for pumping speeds from 47 to 1250 ls-1. They all feature a permanent magnetic upper bearing, which eliminates hydrocarbons at the top of the rotor and an oil lubricated lower bearing for reliable high speed operation. The on-board controller interfaces directly with our TIC and TAG controllers to provide low cost system integration. The nEXT models also allow user serviceability by way of a user changeable bearing cartridge for low cost of ownership. nEXT has been designed to combine all the latest technological advances in Turbomolecular pumps with some new thinking in design for manufacture, delivering a truly class leading product. The nEXT platform brings a high level of modularity to offer maximum flexibility for customer application and requirements. Each pump is available in different internal configurations to offer differing functionality and performance. Our nEXT pumps come in different variants "D" Duplex comes with both turbomolecular and drag stages for improved tolerance to higher backing line pressures. The “D” variants offer superior pumping speed and compression across all gas species. Triplex “T” variants feature turbomolecular, drag and Edwards unique regenerative pumping stages for the ultimate in compression ratio and boost technology for unique vacuum system rationalisation. The "H" variant has been physically tuned to offer an improvement where an application has focus on light gas compression. compression across all gas species.
