Compact, reliable, and energy-efficient, Agilent TwisTorr FS turbomolecular pumps incorporate breakthrough technologies for best-in-class performance, reliability, and quality.

High-performance, high-vacuum pumps with speeds ranging from 70 L/s to 800 L/s

The latest examples of Agilent’s continuing commitment to technological innovation and evolution across its entire range of vacuum solutions, these newest pumps offer:

  • Superior performance: TwisTorr pumps offer the highest pumping speed in their category for all gases, as well as the highest compression ratios for light gases among commercially available turbomolecular pumps.
  • Quiet, low vibration design: Floating Suspension (FS) ensures low vibration and acoustical noise, and optimal bearing working conditions, for extended operating life and excellent stability over time.
  • Easy system integration: The compact, plug-and-play form operates in any orientation; oil-free design avoids contamination of ancillary equipment, and is retrofittable to almost any application.
  • Agilent quality and reliability: Designed and produced to rigorous Agilent quality standards, proven through exhaustive testing and QC, and backed by dedicated technical support.

How it works: Agilent TwisTorr technology

Agilent TwisTorr technology employs a spinning rotor disk that transfers momentum to gas molecules, through the combined actions of centrifugal and centripetal force. Gas molecules follow the spiral groove design on the stator; the pumping effect is repeated for each of the pump’s TwisTorr stages.
