Multiple drag stages

For higher compression ratios and greater backing pressure tolerance

Direct temperature measurements within the pump

Enables wider operating envelope (nEXT55-nEXT85)

Third regenerative stage

Enables boost port options and higher compression (nEXT240, 300, 400)

Patented bearing suspension system

Minimises noise and vibration transmitted to vacuum (nEXT240, 300, 400)

User replaceable oil cartridge

For a speedy interim service and bearing cartridge for a quick low cost scheduled overhaul (nEXT55-400)

Purge port

For safe operation of pump with specialised gases

Permanent magnet upper bearing

For a hydrocarbon free vacuum, reduced vibration and minimum wear

Advanced simulation tool

Derived rotor design to give better speed and compression performance

Manual vent port

With automatic valve accessories for rapid venting and quick cycle times

Manual as well as serial setting of standby speed

For flexible system tuning

Simple parallel operation

Or more sophisticated serial control in both RS232 and RS485 protocols

Automatic wide operating voltage range

From 24V to 48V d.c. for versatility in system integration (nEXT730-1230 48V)

Sensorless drive

For high efficiency and compactness with reduced stray magnetic fields
