Edwards nXDS10iC Chemical Resistant Dry Scroll Vacuum Pump | A73602983
The Edwards nXDS10iC (part number A73602983) is a chemically resistant, oil-free dry scroll vacuum pump designed for applications involving aggressive vapors and solvents. With a pumping speed of 6.7 CFM (11.4 m³/h) and an ultimate vacuum of 0.005 Torr (0.7 Pa), it delivers clean, reliable vacuum without the risk of oil backstreaming or contamination.
The "C" version features enhanced internal components including Chemraz® valve pads and stainless steel fittings, making it significantly more resistant to corrosive gases and chemical vapors compared to the standard nXDS10i.

Key Features & Benefits
- Completely oil-free dry scroll technology – no oil changes required
- Excellent chemical resistance for aggressive vapors and solvents
- Quiet operation at only 52 dB(A)
- Hermetically sealed for ultra-clean vacuum environment
- Long service intervals (up to 5 years for tip seals)
- Integrated inverter drive with speed control
- NW25 inlet and outlet flanges
Technical Specifications
- Pumping Speed: 6.7 CFM (11.4 m³/h) at 60 Hz
- Ultimate Vacuum: 0.005 Torr (0.7 Pa)
- Maximum Inlet Pressure: 0.4 bar absolute
- Noise Level: 52 dB(A)
- Power: 100-127V / 200-240V, 1-phase, 50/60 Hz
- Weight: 26 kg (57 lbs)
Ideal Applications
