Product description:
nEXT240 is a hybrid molecular pump with hybrid bearings. It is supplied with an ISO100 or CF100 inlet flange with 240ls-1 N2
Pumping speed
The pump combines our proven bearing technology (oil-lubricated ceramic lower bearing and dry permanent magnet upper bearing) with an improved rotor design using new molecular grading technology to provide improved pumping speed and compression ratio while providing true User maintainability.
They use 24V to 48V DC sensorless motors with built-in drivers and are fully compatible with our TAG and TIC controller series. The molecular pump has 80W and
160W two kinds of maximum preset power are available. The former applies to our 100W TIC
The controller is also the recommended choice when pumping argon, but the acceleration time to reach full operating speed at this power is relatively long.
A basic pump system may require an nEXT300D pump, a TAG or TIC controller, air or water cooled accessories, or a suitable foreline pump.
Features:
Latest rotor design improves performance for superior pumping speed and compression ratio
End users can complete thorough repairs in a very short period of time, without the need for complicated tools or large unloading … you can do it!
Compact design and excellent performance for efficient systemization
Compatible with Edwards TIC turbine and instrument controllers means you can add up to 3 gauges without the need for additional gauge controllers
RoHS compliant and CSA / UL recognized
