Description
Edwards nXDS dry scroll pumps deliver clean, oil-free vacuum for analytical labs, R&D, and production. Using a fixed and an orbiting spiral, the scroll set traps and compresses gas without sealing oil—eliminating contamination risk and simplifying compliance.
The nXDS10i family advances scroll performance with quiet 52 dB(A) operation, superior vapor handling, intelligent controls, and extended service intervals. Choose from three variants: nXDS10i (standard) , nXDS10iC (corrosion-resistant) , and nXDS10iR (no gas ballast) to match your process environment.
All models run on single-phase 100–240 V, 50/60 Hz power and feature DN 25 ISO-KF (NW25) inlet/outlet for easy integration with common fore line hardware.

FAQ
What’s the difference between nXDS10i, nXDS10iC, and nXDS10iR?
nXDS10i: standard variant for most clean-vacuum applications. nXDS10iC: corrosion-resistant materials for aggressive vapors. nXDS10iR: variant without gas ballast for processes requiring the lowest contamination risk.
Are these pumps oil-free?
Yes. They are dry scroll pumps—no sealing or lubrication oil in the vacuum space, minimizing contamination and maintenance.
What applications are they suited for?
Analytical instruments (GC/MS, LC/MS), vacuum ovens and dryers, gloveboxes, sample prep, thin-film processes, and general lab/production roughing.
What maintenance is required?
Periodic tip-seal replacement and routine checks of filters and gas ballast accessories. Long service intervals help maximize uptime.
How loud are the pumps?
Approximately 52 dB(A), quiet enough for benchtop and lab environments.
Frequently asked questions
What is the difference between the i, iC and iR variants?+
nXDS10i is the standard pump, nXDS10iC is corrosion-resistant for aggressive process environments, and nXDS10iR is supplied without gas ballast.
How does a dry scroll pump work?+
A fixed and an orbiting spiral trap and compress gas without sealing oil, which Edwards describe as eliminating contamination risk and simplifying compliance.
What are the inlet and outlet connections?+
DN 25 ISO-KF (NW25) on both, for integration with common fore line hardware.
What power supply does it need?+
Single phase, 100–240 V, 50/60 Hz.
How does it handle water vapour?+
Edwards specify superior water-vapour tolerance, which they note broadens the application range from drying through to analytical sample preparation.
What certifications does it carry?+
The product data lists CE, UL and CSA, with IP20 protection.
