The TwisTorr 304 FS is a new high-vacuum pump featuring floating-suspension technology. This technology can be used 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 liters per second for N2. It also provides dramatic improvements in reliability and increases light gas compression ratios hundredfold. 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.
