Agilent Varian TwisTorr 305-FS turbomolecular high-vacuum pumps have new and improved performance over the previous 304-FS turbo pumps. These improvements include newer labyrinth designed TwisTorr drag stage technology, Agilent Floating Suspension (AFS), and optimized thermal design mapping.

TwisTorr drag stages create high compression ratios for light gases such as Hydrogen and Helium and deliver high throughput and high tolerance of foreline pressure, thereby permitting the use of smaller and more economical backing pumps. Drag Stage technology results in a compact rotor design that is energy-efficient and maintains a low operating temperature.

The Agilent Floating Suspension System (AFS) reduces noise and vibration, and ensures optimal bearing operating conditions that extend operating life, minimize system downtime, and assure stable pumping performance over long periods of time. Unique ceramic ball bearings with permanent lubrication eliminate oil and maintenance, and permit operation of the pump in any orientation.

The model 305-FS requires an outboard remote controller unit for operations. The 305-IC version has a sleek onboard integrated controller built into the side of the pump.

Agilent turbo pumps are designed for optimum performance in real world applications and include integration of pumping systems and multi-flow pumps. Compact sized pumps meet the needs of industries with stringent space requirements. These new Agilent TwisTorr 305-FS turbo pumps require minimal to no maintenance and provide protection from misuse. These pumps go through a variety of quality and reliability tests which include: Long life, Shock, Vibration, Packaging, Thermal, Quiet and Noise. For a detailed explanation of these tests see the brochure download below.

The Agilent Varian TwistTorr 305-FS turbo pump with CF 6 inch flange has a pumping speed of 255 l/s of nitrogen, KF-16 foreline flange and ambient operating temperature from 5 °C to 35 °C. Startup time is 3 minutes. Rotational speed 60,000 rpm. Recommend foreline pumps are dry IDP-3, IDP-7, IDP-10, or wet DS-102, DS-302. The cooling requirements are a minimum of forced air when conditions are 5- 35 °C ambient air temperature, or water cooling with minimum flow: 50 l/h (0.22 GPM) with water temperature between +15 °C to +30 °C at a water pressure max of 5 bar (75 psi.) This unit is ambient air cooled but a water cooled unit is available.

These pumps can use the new Vacuum Link App. available for Apple or Android smartphones, via Bluetooth, USB or NFC communications. This app allows for real-time monitoring of the parameters of your choice and offers recording capabilites and data export to your computer for display and sharing. The app can be downloaded off Agilent's Website. For more technical information on the 305-FS, see the brochure and operating instructions downloads below.
