TwisTorr FS Family

Innovation expands

The new TwisTorr FS Turbo Pump family

Vacuum beyond specifications

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

Welcome to the family: New medium-size 404 FS, 704 FS, and 804 FS turbo pumps

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.
