Edwards nXDS20i Oil-Free Dry Scroll Vacuum Pump – 13 CFM (A73801983)
The Edwards nXDS20i (part number A73801983) is the highest-capacity pump in the nXDS series of oil-free dry scroll vacuum pumps. With a pumping speed of 13 CFM (22 m³/h) at 60 Hz and an ultimate vacuum of 0.022 Torr (0.030 mbar), it delivers powerful, clean vacuum performance without the risk of oil contamination or backstreaming.
Designed for demanding laboratory and light industrial applications, the nXDS20i features hermetically sealed bearings, an integrated inverter drive, and intelligent controls for quiet, efficient, and reliable operation with extended service intervals.
Key Features & Benefits
- Completely oil-free dry scroll technology – no oil changes or disposal required
- Highest pumping speed in the nXDS range for faster evacuation
- Very quiet operation at only 52 dB(A)
- Hermetically sealed for ultra-clean vacuum environment
- Excellent water vapor handling with gas ballast
- Long tip seal life – up to 5 years in many applications
- Low power consumption and compact footprint
- NW25 inlet and outlet flanges
