Edwards nXDS6iC Chemical-Resistant Oil-Free Dry Scroll Vacuum Pump – 3.6 CFM (A73502983)
Edwards nXDS6iC Chemical-Resistant Oil-Free Dry Scroll Vacuum Pump – 3.6 CFM (A73502983)
The Edwards nXDS6iC (part number A73502983) is a compact, corrosion-resistant oil-free dry scroll vacuum pump designed for applications involving aggressive chemical vapors, solvents, and corrosive gases. With a pumping speed of 3.6 CFM (6.2 m³/h) at 60 Hz and an ultimate vacuum of 0.005 Torr (0.7 Pa), it delivers clean, reliable 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 nXDS6i when handling harsh or reactive vapors.
Key Features & Benefits
- Completely oil-free dry scroll technology – no oil changes required
- Superior corrosion resistance for aggressive vapors and solvents
- Compact and lightweight design for benchtop use
- 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
- NW16 inlet and NW25 outlet flanges
