nEXT & EXT - REBUILT
Edwards small EXT70 uses a magnetic upper bearing and a ceramic lower bearing. In the EXT250M the rotor is entirely supported by magnetic bearings and can be mounted in any orientation. In the EXT70H the letter H signifies compound molecular: combined bladed turbomolecular stages with molecular drag stages on the same rotor. View our inventory of Edwards turbo controllers.
