On-board control for running at reduced power
Controller adds electronic braking, smart cooling fan, and automatic vent options
Compatible with Edwards TIC Turbo and Instrument Controller, enabling you to add one or more vacuum gauges without the need of an additional display controller
Gas purge port for process gas dilution to protect motor and lower bearing

New range of hybrid bearing compound turbomolecular pumps
Proven bearing technology (oil lubricated ceramic lower bearing with dry permanent magnetic upper bearing)
Fully compatible with TIC controllers/bearings—nEXT pumps are all easily field-serviceable using a simple tool to change both the bearing and oil reservoir
Innovative new suspension system means that no rebalancing of the rotor is required, eliminating the need for expensive jigs, fixtures, and measuring equipment during service
