The TwisTorr 404 FS offers 400 L/s pumping speed in DN 100 installations, high compression ratios for light gases, and features the trademarked Agilent floating suspension (AFS), ensuring low vibration and noise level for compatibility with sensitive environments. The high compression ratios, high foreline pressure tolerance, and maintenance-free operation make the TwisTorr 404 FS a high-performance, reliable, and low-cost-of-ownership pump to operate.

The 404 FS is an excellent choice for UHV systems, nuclear research, ion implanters, surface analysis, electron microscopy, and cryogenics applications. The pump’s smart controller automatically optimizes pump performance according to system needs.
