Edwards nXDS20iR Dry Scroll Vacuum Pump with Integrated Inverter and Gas Ballast
Product Description
The Edwards nXDS20iR is a high-performance dry scroll vacuum pump designed for specialist uses such as gas recirculation and rare gas recovery. Key features include:
- Pumping capability: Exceptional speed with improved performance over legacy XDS models
- Ultimate vacuum performance: Lower ultimate pressures achieved
- Power efficiency: Reduced power consumption
- Noise reduction: Up to 20 times quieter than comparable pumps
- Gas ballast: Enables pumping of condensable vapors including water, solvents, dilute acids, and bases
- Tip seal technology: Latest design extends operating life between tip seal changes
- Integrated inverter drive: Auto sensing voltage input ensures optimized global performance
- Special design: Unlike the standard nXDS20i, the nXDS20iR is specifically engineered to minimize gas dilution and seal integrity for sensitive applications
This combination of features makes the nXDS20iR suited for applications requiring minimal gas loss, effective handling of condensable contaminants, and quiet, efficient operation.
