nEXT240, nEXT300 and nEXT400

A wide variety of sizes:

Giving OEMs and end users a greater choice and the flexibility to tailor the most appropriate vacuum solution to meet their individual needs.

Each is available in two variants:

– 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.

See Boost technology custom interface split flow variants are also available in three sizes for further vacuum system optimisation.

The ‘A’ variant: Advanced variants optimized for UHV and R&D applications:
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.

Field replaceable oil cartridge and bearing assembly:
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.

Low power consumption and standby mode:
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.

Compact design:
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.
