Edwards STP-iX455 Turbomolecular Pump

The Edwards STP-iX455 represents the pinnacle of high-vacuum engineering, featuring an advanced, digitally controlled 5-axis magnetic levitation system paired with a fully integrated onboard controller. By eliminating the need for bulky, traditional rack-mounted control units and heavy interconnecting cables, this all-in-one design delivers an exceptionally small footprint and dramatically simplifies tool integration.

Designed specifically for vibration-sensitive and high-uptime environments—such as electron microscopy, metrology, lithography, and high-energy physics research—the STP-iX455 offers an unparalleled clean, hydrocarbon-free high vacuum with virtually zero routine maintenance.

• Integrated Drive Controller: True plug-and-play architecture reduces installation costs and saves valuable rack space. Operates on a standard $48\text{V DC}$ input (compatible with the Edwards iPS-240 AC power supply unit).

• Ultra-Low Vibration: The self-sensing magnetic bearing system combined with Automatic Vibration Reduction (AVR) delivers a 50% reduction in vibration amplitudes compared to previous-generation turbo pumps.

• Maintenance-Free Operation: Zero frictional contact points mean no bearing wear, no oil lubrication requirements, and zero risk of process contamination.

• Flexible Orientation: Can be mounted and operated reliably in any physical orientation.

• Advanced Diagnostics: Real-time monitoring and digital interface capabilities ensure maximum tool uptime and early anomaly detection.
