Description
Edwards nXDS10i Dry Scroll Vacuum Pumps (Standard, C, R) | USA Lab
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.
Oil-Free / Dry Scroll Quiet 52 dB(A) DN25 ISO-KF Ports IP20 Rated Single-Phase 100–240 V CE • UL • CSA
Oil-free vacuum: hermetically sealed scroll set for contamination-free processes and no oil disposal.
Low maintenance: long service intervals and easy tip-seal changes reduce downtime and cost of ownership.
Vapor handling: superior water-vapor tolerance broadens applications from drying to analytical sample prep.

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.
