Edwards XDS46i Oil-Free Dry Scroll Vacuum Pump – 23.5 CFM (A73101983)
The Edwards XDS46i (part number A73101983) is a high-capacity, oil-free dry scroll vacuum pump from the XDSi series. With a peak pumping speed of 23.5 CFM (40 m³/h) and an ultimate vacuum of 0.04 Torr (0.05 mbar), it is optimized for high-throughput applications, particularly as a reliable backing pump for turbomolecular pumps in mass spectrometry (LCMS, ICPMS) and other analytical instruments.
The XDS46i features an innovative bearing shield that completely isolates the bearings and lubricant from the vacuum space, ensuring a totally clean, oil-free vacuum with minimal maintenance and long service life.
Key Features & Benefits
- Completely oil-free dry scroll technology – no oil changes or contamination risk
- High pumping speed optimized for inlet pressures between 1–10 mbar
- Very quiet operation (55.4 dB(A))
- Hermetically sealed bearings for clean vacuum
- Excellent for backing turbomolecular pumps
- Integrated inverter drive for consistent performance worldwide
- Robust design with long tip seal life
- NW40 inlet and NW25 exhaust flanges
