Dry Scroll Pumps
Dry scroll vacuum pumps are positive displacement pumps that use two spiral-shaped scrolls, one fixed and one orbiting, to trap and compress gas molecules. They are oil-free, low maintenance pumps that are commonly used for clean vacuum applications. Since they do not rely on oil for sealing and lubrication, they eliminate the risk of oil contamination and leakage, making them an environmentally-friendly choice.
We in Edwards are driving scroll technologies to its best and we are committed to offer the most sustainable solution now and in the future.
nXDSi Scroll Pumps
Edwards nXDS is the great new shape of dry vacuum pumping.
The nXDS has taken scroll vacuum technology to the next level. Improved performance, exceptional pumping capability, quiet operation and extended service intervals make nXDS the ultimate dry choice. The range covers pumping speeds from 6 to 20 m3/h.
nXDS15i
The nXDS15i same as the nXDS10i are our key products offering a small dry pump solution for most Scientific Applications. Standard variant suitable for a large variety of applications; R-variant with blanked gas ballast and C-variant being corrosion resistant.
nXDS15iC - 100-127/200-240V 1Ph 50/60Hz
The nXDS15iC has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications involving corrosive substances. This chemically resistant version is fitted with Chemraz® internal valve pads and stainless steel fittings.
