New High-Vacuum Pump Provides Increased Reliability and Efficiency

A new, high-performance turbomolecular pump is the first high-vacuum pump featuring a novel floating-suspension system that enables dramatic improvements over current technology.

Agilent Technologies (Santa Clara, CA, USA) introduces the TwisTorr 304 FS vacuum pump for use in a variety of applications and markets, including academic and government research, and the analytical, industrial, and nanotech/semiconductor industries. Running at 60,000 rpm, it pumps up to 250 L/s for N2. It also provides dramatic improvements in reliability and increases light gas compression ratios 100-fold. TwisTorr drag stages guarantee high pumping speed and compression ratios for hydrogen and helium. The pump also provides unparalleled throughput and high foreline tolerance, as well as low power-consumption and operating temperature.

Coupled with the same superior performance as in Agilent’s existing line of patented TwisTorr solutions, the new system's breakthrough floating-suspension technology ensures low vibration and acoustical noise, optimal working conditions for the bearings, extended operating life, and exceptional stability for demanding applications and instruments such as scanning electron microscopes. It also features a compact rotor design that reduces power consumption and system footprint. Its unique bearing and dry lubricated suspension system is maintenance-free, eliminates oil and risk of contamination, and permits installation in multiple orientations.

"The new TwisTorr 304 FS is the smallest, most reliable, and energy-efficient high-vacuum pump available today," said Giampaolo Levi, vice president and general manager of Agilent's Vacuum Products Division; "[...] and we will continue our active collaboration with customers to identify their expanding needs and develop new advances in turbo pump design."
