EDWARDS brand guide / Product family
The nEXT family serves high-vacuum pumping duties, with different capacities, inlet connections and configurations.
nEXT selection requires the gas-specific pumping speed, inlet connection and backing arrangement. Cooling, controller, cables and venting must suit the chosen configuration. Chamber volume, gas throughput and pipework conductance affect pump-down and working pressure. Use the linked model information to compare these conditions.
Select by gas-specific pumping speed, required pressure and inlet flange. Check backing pressure, cooling, controller and cable requirements alongside the turbo pump.
Compare nXDS dry scroll backing pumps. Match backing pressure, throughput and gas compatibility to the selected turbo and process; flange size alone does not establish compatibility.
Compare values with their stated gas, frequency and configuration conditions. A blank specification means it needs confirmation. Listed equipment is subject to a quotation; inclusion here does not indicate stock.
