Turbomolecular Pump
SF400/3500 turbine molecular pump is a mechanical vacuum pump, through high-speed rotary multi-level turbine rotor blade and stationary turbine leaves a combination of exhaust, at the molecular flow to the region have been pumping gas high compression ratio, from obtaining the required vacuum performance, was pumping gas to non-selective, non-memory effect, operation simple, user-friendly. Owing to the large molecular weight highly compressed gas than, and in the course of operation, will not be subject to regional high vacuum steam oil pollution, the oil pump back plate is cold and sinks can obtain high vacuum and ultrahigh vacuum cleaner environment. It is widely used in surface analysis, accelerator technology, plasma technology, electron tubes and vacuum manufacturing technology in various fields.
