Edwards nXR120i – compact dry vacuum pump
The nXRi pumps are multi-stage Roots pumps with a pumping speed of 30 to 120 m³/h in a very small housing. The nXR120i reaches 120 m³/h and an ultimate pressure of 0.03 mbar; at 29 kg it fits under a laboratory bench and remains portable.Features
- Pumping chamber free of oil and dust – no contamination of the process, no oil smell
- Single-phase control for 100–127 V and 200–240 V, 50/60 Hz: same performance worldwide
- Operation at the unit or remotely via parallel or serial interface; USB port for monitoring with the Edwards nST2 software
- Additional connection for switching valves automatically, e.g. a vacuum isolation valve as protection in the event of a power failure
Typical applications
Edwards names analytical instruments (electron microscopy, mass spectrometry, residual gas analysis, leak detection), research (UHV, high-energy physics) and industrial applications such as drying, plasma cleaning and the regeneration of cryopumps.Advice and service
