nXRi - dry multi stage roots

Environmental friendly backing pump with zero contamination and 5 years interval between service.
the nXRi fits easily under a benchtop saving valuable space
in your laboratory
Energy efficiency
optimised to low power for lower energy costs and reduced heat load from your vacuum equipment
Unrivalled performance
It delivers four times more pumping speed than similar sized dry pumps, and with low ultimate and high reliability you are assured a consistent and
stable vacuum for years to come
Zero contamination
Clean processes and clean results are guaranteed with the nXRi
compact dry pump, being totally oil-free and dust-free within the
vacuum chamber.
Edwards has revolutionised the vacuum pump market with the new nXRi high performance, compact dry pump. It delivers unrivalled pumping speeds in the most compact package, with pumping speeds of 30, 40, 60, 90 and 120 m3 h-1. The nXRi's lower input power and zero maintenance create real performance improvements and cost benefits across a range of applications.
Analytical Instrument OEMs benefit from the ease of integration into most vacuum systems for a ready to go vacuum solution, perfect for mass spectrometry, electron microscopy and leak detection.
R&D and industrial customers will enjoy the design flexibility, oil-free and low maintenance features.
