Edwards nXDS6i / nXDS6iC / nXDS6iR Dry Scroll Vacuum Pumps | USA Lab
The Edwards nXDS6 series provides compact, oil-free dry scroll vacuum performance for laboratories, analytical systems, and process applications that require clean vacuum, low maintenance, and reliable operation. The family includes the standard nXDS6i, corrosion-resistant nXDS6iC, and nXDS6iR variant supplied without gas ballast.
Each pump features DN 25 ISO-KF (NW25) inlet and vacuum outlet connections, quiet 52 dB(A) operation, forced-air cooling, and a compact design suitable for benchtop or equipment-rack installations. The pumps support universal single-phase 100–127/200–240V, 50/60Hz power and include UL, CSA, CE, and EAC certifications for broad equipment integration.
With dry scroll technology, IP20 protection, DX protocol communication, and rough-vacuum capability, the Edwards nXDS6 family helps reduce contamination risk and routine maintenance while delivering dependable vacuum performance for research, analytical, pharmaceutical, chemical, and pilot-scale workflows.

FAQ
What are the differences between the Edwards nXDS6i, nXDS6iC, and nXDS6iR?
The nXDS6i is the standard dry scroll pump, the nXDS6iC uses corrosion-resistant materials and seals for applications involving more aggressive vapors, and the nXDS6iR is configured without gas ballast for applications that do not require vapor-handling capability.
Are the Edwards nXDS6 pumps oil-free?
Yes. The Edwards nXDS6 series uses dry scroll technology and does not use oil in the vacuum path, helping reduce contamination risk and eliminating routine oil changes.
What vacuum connections are used on the Edwards nXDS6 pumps?
The nXDS6i, nXDS6iC, and nXDS6iR models use DN 25 ISO-KF (NW25) connections for both the inlet and vacuum outlet.
Is a power cable included with the Edwards nXDS6 pumps?
The mains power cable is not included and must be selected according to the installation region. Gas ballast, inlet filters, and certain other vacuum accessories are also selected separately.
