Edwards xNXS6i Oil-Free Dry Scroll Vacuum Pump

This nXDS6i dry scroll pump range from Edwards has exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features. The Edwards nXDS6i is the best performing pump in its class. The nXDS6i is up to 20 times quieter than other pumps. Its intelligent control functions and up to five year service interval offer low cost of ownership, making it the small dry pump of choice for today’s most advanced technologies.

The Edwards nXDS-6i, nXDS 6i, pumps are truly dry vacuum pumps as all the bearings, with their hydrocarbon lubricant, are isolated from the vacuum space. The nXDS6i is the next generation in completely oil free, dry scroll pumps and replaces the XDS5. nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise. Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimized pumping performance globally. nXDS pumps are designed to be completely field serviceable.
