Cooling Kit Required, Agilent Varian Part Number PN: X3502-64171.

These Agilent Varian TwisTorr 74 FS turbomolecular vacuum pumps have a KF-40 inlet flange, with 44 L/S pumping speed, and have the Agilent Floating Suspension with patented TwisTorr drag stages. The 74 FS model is a reliable compact turbo pump, its 1167 Hz drive frequency allows for long bearing life, and is an economic-dependable pump for high-vacuum applications. They have improved performance, including a newly designed labyrinth Twistorr drag stage technology, and the Agilent Floating Suspension (AFS) along with optimized thermal design mapping. This 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 to extend life, minimize system downtime, and assure stable pumping performance over long periods of time. The unique ceramic ball bearings with permanent lubrication eliminate oil and maintenance, and permit operation of the pump in any orientation. 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. These Agilent Varian 74 FS turbomolecular high-vacuum pumps have an KF-40 inlet flange, an ultimate pressure of 1x10-8 Torr (which is limited by outgassing from the rubber O-ring seal in the intake KF centering ring), and have an Agilent Varian part number X3502-64171. The Conflat version, with all metal-sealed conflat intake gasket, are true ultra-high vacuum pumps having an ultimate pressure as low as 3.75x10-10 Torr when used correctly. These TwisTorr 74-FS turbo pumps require an outboard remote rack-mount or onboard pump-side-mounted controller. The required turbo pump cooling kit, either fan forced-air or water cooling, are sold separately.

These Agilent Varian TwistTorr 74 FS turbo pumps have an NW40 Inlet flange, has a pumping speed of 44 l/s of nitrogen, a KF-16 foreline flange, and ambient operating temperature from 5 °C to +35 °C. These 74 FS turbo pumps have a start up time of less than 2 minutes, rotational speed of 70,000 rpm, and recommended foreline roughing pumps of either dry scroll (IDP-3 or IDP7) or oil-sealed rotary vane (DS-40M or DS-102). The cooling requirements for forced-air cooling are ambient air temperature of 5 to 35 °C or with water cooling are a minimum flow of 0.30 gpm, between 15 to 25 °C at 45 to 75 psi.
