Notes on the Edwards nEXT85D Hybrid Turbomolecular Vacuum Pump
Edwards nEXT85D 24V turbo molecular high vacuum pump with Conflat CF 4.5 inch CFF63 Inlet. Pump has a Pumping Speed of 61 liters per second (l/s) and ultimate pressure of 5x10-9 Torr. The Edwards nEXT85D 24V turbo molecular pump with Conflat CF 4.5 inch CFF63 Inlet and KF-16 exhaust fore line flange. The Edwards nEXT85D 24V turbo molecular pump can be used for all general-purpose high vacuum applications. The nEXT85D pumps consist of the compound turbomolecular pump with a permanently attached Podule containing drive electronics. The Podule controls the electrical supply to the pump. It has no manual controls and can only be operated through the logic interface. To operate the nEXT85D pump you must connect it to your own control equipment and power supply or alternatively use the Edwards TIC Turbo Instrument Controller, TIC Turbo Controller No Instrument or TAG Controller. The Podule drives the brush-less d.c. motor in the pump. The pump has three Hall effect devices that operate as rotor position sensors and ensure that the drive current is correctly commutated around the motor phase windings. The vacuum pump contains turbomolecular blades and a Holweck drag mechanism on a single shaft; the Holweck mechanism allows operation at higher backing pressures than pure turbomolecular pumps. The DX pumps have a vent-port for venting the pump and vacuum system to atmospheric pressure. The pump is supplied with a manual vent-valve fitted; this can be replaced with a TAV5 (PN P105358) or TAV6 (PN P106355) solenoid-operated vent-valve available on this website.

The DX pumps have a purge-port: an inert purge gas can be introduced to protect the bearing and motor from corrosion, or the bearing lubricant from oxidation. 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. The Podule contains the drive electronics that control the pump operation and accessories such as a TAV vent valve or air cooler. There is a connector socket on the top of the Podule where the TAV vent valve or air cooler can be plugged-in. The Podule has two indicator LEDs that signal the status and operation of the pump, that can also be used for faultfinding if a problem should occur. The drive electronics system has a number of built-in safety features to protect the DX pumps from damage in the event of sustained high pressure or temperature. See manual below for specifics. An Air cooling fan kit is also supplied. (Roughing pump not included.) The complete specifications and application brochure in PDF format can be downloaded below.

Notes on the TAG Turbo and Active Gauge Controller
The Edwards Turbo and Active Gauge (TAG) controller is a small low cost pumping system controller, suitable for a wide range of vacuum applications and compatible with all Edwards EXT and nEXT turbo pumps. The large LED display shows the pump speed or vacuum pressure and an easy to use push button interface enables ease of operation and control. TAG controllers will also run a backing pump, air vent valve an air cooler and an Edwards active gauge, making the TAG a versatile system controller. This compact 24 VDC TAG controller (with external power supply) is ideal for use on bench-tops or suitable for mobile platforms where space is limited yet functionality and reliability are essential. These Edwards TAG turbo pump controllers are designed to operate nEXT85D, nEXT 240, 300 and 400 turbo pumps. The complete specifications and application brochure in PDF format can be downloaded below.
