The Agilent 400 L/s medium turbo pump, TwisTorr 404 FS, combines TwisTorr drag stage technology and Agilent Floating Suspension (FS) to provide high performance, reliability, and economy.

This 400 liter turbomolecular pump delivers high vacuum performance thanks to the synergy between turbo technology and innovative TwisTorr drag stages. Floating Suspension assures low vibration and acoustical noise for compatibility with sensitive instrumentation and work environments.

The TwisTorr 404 FS is perfectly suited for a wide range of applications, including research and development, UHV systems, nuclear research, ion implanters, surface analysis, electron microscopy, and cryogenics.

Agilent also provides TwisTorr FS-OS turbo pumps, designed for academia, research, and other applications that require long-term operation in demanding conditions.

Key features

• Innovative TwisTorr technology – high compression ratio for light gases, such as Helium and Hydrogen, 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.
