Edwards nXDS20iC Corrosion-Resistant Oil-Free Dry Scroll Vacuum Pump – 13 CFM (A73802983)
The Edwards nXDS20iC (part number A73802983) is a high-capacity, corrosion-resistant oil-free dry scroll vacuum pump designed for demanding applications involving aggressive chemical vapors, solvents, and corrosive gases. With a pumping speed of 13 CFM (22.0 m³/h) at 60 Hz and an ultimate vacuum of 0.022 Torr (0.030 mbar), it delivers powerful, clean vacuum performance without oil contamination or backstreaming risks.
The "C" version features enhanced chemical resistance with Chemraz® internal valve pads and stainless steel fittings, making it significantly more durable than the standard nXDS20i when handling harsh vapors.
Key Features & Benefits
- Completely oil-free dry scroll technology – no oil changes required
- Superior corrosion resistance for aggressive vapors and solvents
- Highest pumping speed in the nXDS series for faster evacuation
- Very quiet operation at only 52 dB(A)
- Hermetically sealed for ultra-clean vacuum environment
- Excellent water vapor and solvent handling with gas ballast
- Long tip seal life and low maintenance
- NW25 inlet and outlet flanges
