Edwards nEXT85H NW40 NW16 80W Turbomolecular Vacuum Pump Ultimate Vacuum <5x10-9 mbar Inlet Conne (more)ction NW40 Pumping Speed Nominal 2,820.00 l/min Features - Combines oil-lubricated ceramic and dry permanent magnetic bearings for enhanced durability - Built-in electronics for streamlined operation and easy integration with control systems - Enhances speed and compression efficiency for a wide range of applications - Allows for in-field replacement of oil cartridges and bearings with minimal tools - Offers standard, high light gas compression, and additional regenerative stage options for specific needs - Provides superior compression performance for various gases - Ensures efficient operation with reduced electrical interference - Magnetic bearings reduce noise and vibration, ensuring a stable vacuum environment The nEXT 85H pumps consist of the turbomolecular pump with a permanently attached controller containing drive electronics. The controller controls the electrical supply to the pump with the exception of standby speed control. It has no manual controls and can only be operated through the logic interface. To operate the nEXT-85 H pump you must connect it to your own control equipment and power supply or alternatively use the Edwards TIC Turbo Instrument Controller or TIC Turbo Controller. nEXT 85H pumps are supllied with an inlet-screen fitted into the centering O-ring for ISO version pumps and into envelope for CF version pumps. nEXT85 pumps with an NW 25 interstage-port are supplied with an inlet-strainer that fits into the interstage-port. The inlet-screen and inlet-strainer protect the pump against damage that would be caused by debris entering the pump. The nEXT 85 H pumps have a vent-port for venting the pump and vacuum system to atmospheric pressure. The pump is supplied with a manual vent-vavle fitted; this can be replaced with a TAV5 or TAV6 solenoid-operated vent-valve. The TAV valve can be directly controlled by the on-board controller. The nEXT pumps have a purge-port: an inert purge gas can be introduced protect the bearing and motor from corrosion. An optional vent-port adapter and purge restrictor can be fitted to the purge-port to control the flow rate of the purge gas and to filter the gas supply.
