nXRi - dry multi stage roots

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 60 and 90 m3 h-1. The nXRi's lower input power and zero maintenance create real performance improvements and cost benefits across a range of applications.

Compact footprint

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.
