Edwards nXDS6iR Dry Scroll Pump is a high-performance vacuum solution designed for demanding laboratory and industrial processes. Unlike standard models, the nXDS6iR is specially engineered for applications such as gas recirculation, rare gas pumping, and recovery — where minimizing dilution and ensuring gas integrity is critical.
Key Features:
- Bearing shield design keeps process gases separated from bearing lubrication, ensuring a clean vacuum and eliminating contamination risks.
- Smart motor drive enables global voltage compatibility, protects against overload, and offers remote start/stop capability.
- High-flow gas ballast allows pumping of vapors, including water vapor, up to 240 g/h.
- Single-sided scroll mechanism makes tip seal maintenance quick and easy, reducing downtime and ownership costs.
- Enhanced versions achieve up to 20% lower peak power during initial pump down.
- Up to 20 times quieter than comparable pumps — only 52 dB(A).
- Integrated inverter drive with auto-sensing voltage optimizes pumping performance worldwide.
- Tip seal technology extends intervals between changes for reliable, long-term use.
- Standard manual gas ballast port supports condensable vapors like water, solvents, dilute acids, and bases.
- Perfect companion pump for turbomolecular applications.
