Edwards nEXT Turbo Molecular Pumps 

Overview

A turbo molecular pump is a multistage axial-flow turbine in which high speed rotating blades provide compression by increasing the probability of gas moving in the pumping direction. The turbo molecular pump is optimized for molecular flow conditions and requires a suitably sized backing pump to exhaust to atmosphere. The Edwards nEXT series of turbo pumps have been designed to combine all the latest technological advances in turbo molecular pumps providing end-user serviceability and delivering a truly class leading product. Pump sizes available offering true 85, 240, 300, 400 and we have now added 700 and 900 liters per second pumping speed performance to our nEXT family(N2).

The pump has been totally re-designed to optimize performance and achieve both greater speeds and higher compressions, while maintaining increased levels of reliability in a small package.
