Proper bearing protection can increase the service life and uptime of a pump. Oerlikon Leybold Vacuum’s Turbovac i line of turbo molecular pumps with integrated drive electronics have ceramic bearings that are protected against heat and contamination. The 350 i and 450 i are suitable for ultra-high vacuum applications and for integration within compact pump system solutions. Designed for processes with small backing pumps, they provide high gas throughput, fast run-up time and insensitivity to particulates. The 350-400 i Multi Inlet pumps provide a high degree of flexibility for analytical instrumentation and allow the customization of the number, height and position of the vacuum connections.
