TwisTorr 704 FS

The Agilent TwisTorr 704 FS turbomolecular high-vacuum pump combines TwisTorr drag stage technology and Agilent Floating Suspension to provide high performance, reliability, and economy. TwisTorr drag stages create high compression ratios for light gases such as hydrogen and helium to deliver high throughput and high tolerance of foreline pressure, thereby permitting the use of smaller and more economical backing pumps. This technology results in a compact rotor design that is energy-efficient and maintains a low operating temperature. The Agilent Floating Suspension system reduces noise and vibration, and ensures optimal bearing operating conditions to extend operating life, minimize system downtime, and assure stability over time. The unique bearing and dry lubrication in the TwisTorr 704 FS eliminate oil and maintenance, and permit operation of the pump in any orientation. Available with onboard or rack controllers.


  • Innovative TwisTorr technology - high compression ratio for light gases provides high performance and minimal system footprint.
  • High foreline tolerance - permits use of smaller backing pump, thereby reducing system cost and size.
  • Agilent Floating Suspension - low vibration and acoustical noise as well as optimal bearing working conditions extend operating life to optimize cost-of-ownership, minimize system downtime, and assure stable performance over time.
  • Unique bearing and dry lubrication - maintenance free, oil free; allows installation in any orientation.
  • “Three dimensional” pump control software provides maximum flexibility, speed, and simplicity - for the best throughput and compression performance according to the operating conditions of the pump.
  • Typical Turbo Pump Applications
