Each is available in two variants:<\/span><\/span><\/p>\n\n\n\n

– the D-variant combines turbo and drag stages;
– the T-variant adds Edwards unique fluid dynamic stages and the option of additional booster ports for increased system rationalisation.<\/p>\n\n\n\n


See Boost technology custom interface split flow variants are also available in three sizes for further vacuum system optimisation.<\/p>\n\n <\/div>\n <\/div>\n\t<\/div>\n<\/section>\n<\/div>\n\n\n\n

The ‘A’ variant: Advanced variants optimized for UHV and R&D applications:<\/span><\/span>
The nEXT300 and nEXT400 models have been further enhanced with the introduction of the Holweck technology. This design significantly improves light gas compression ratios, making these pumps exceptionally well-suited for ultra-high vacuum (UHV) applications and research and development (R&D) environments. The new variant offers superior performance and reliability, ensuring optimal efficiency and effectiveness in demanding scientific and R&D applications.<\/p>\n\n <\/div>\n <\/div>\n\t<\/div>\n<\/section>\n<\/div>\n<\/div><\/div>\n\n\n

Field replaceable oil cartridge and bearing assembly:<\/span><\/span>
The pumps feature a field replaceable oil cartridge and bearing assembly and the user is notified as to when service intervention is required.
This enables easy maintenance as users can carry out servicing in-house, which reduces the cost of ownership.<\/p>\n\n <\/div>\n <\/div>\n\t<\/div>\n<\/section>\n<\/div>\n\n\n\n

Low power consumption and standby mode:<\/span><\/span>
The efficient pumps have low power consumption and also feature a standby mode, which allow users to make further energy savings.
nEXT240-300-400 pumps have extra low vibration and low magnetic field signature variants for sensitive electron microscope applications.<\/p>\n\n <\/div>\n <\/div>\n\t<\/div>\n<\/section>\n<\/div>\n\n\n\n

Compact design: <\/span><\/span>
The compact design means the pumps fit together neatly in high product density applications.
They are easy to configure and have an intelligent control interface accepting a 24 to 48Vdc input power supply voltage range and can be controlled using a simple parallel control or serial communications in both RS232 or RS485 formats.<\/p>\n\n <\/div>\n <\/div>\n\t<\/div>\n<\/section>\n<\/div>\n<\/div><\/div>\n\n\n
