Edwards nXDS20iC Dry Scroll Pump sets a new benchmark for vacuum performance in its class. Engineered with innovative features, it delivers exceptional pumping capabilities, improved ultimate vacuum levels, reduced power consumption, and quieter operation—up to 20 times quieter than comparable pumps. Its enhanced design, including Chemraz internal valves and stainless steel fittings, makes it ideal for handling more aggressive applications.
Key Features:
- Bearing shield keeps process gases separate from bearing lubrication to ensure a clean vacuum and eliminate contamination risks
- Smart motor drive offers global voltage compatibility, pump overload protection, and remote start/stop capability
- High-flow gas ballast allows pumping of condensable vapors—including water—at up to 240 g/h
- Single-sided scroll design simplifies maintenance, reducing service time and cost
- Enhanced models reduce peak power demands by up to 20% during initial pump down
- Integrated inverter drive with auto-sensing input for optimized global performance
- Manual, easy-to-use gas ballast port included
- Perfect companion pump for turbomolecular systems
- Latest tip seal technology extends service intervals for lower cost of ownership
