The nEXT300D is a hybrid-bearing compound turbomolecular pump. nEXT pumps combine our proven bearing technology (oil-lubricated ceramic lower bearing with dry permanent magnetic upper bearing), an improved rotor design with a new molecular drag stage to deliver improved pumping speed and compression ratios, and user serviceability. They feature 24 V to 48 V d.c. sensorless motors with a built-in drive that is fully compatible with our range of TAG and TIC controllers. They are available pre-set for either 80 W or 160 W maximum power, the former enabling use with our 100 W TIC controllers is also recommended for pumping Argon, but with a longer ramp time to full operating speed.

A basic pumping system includes a nEXT300D pump, a TAG or TIC controller, an air or water cooler, or a suitable backing pump.
