The nEXT 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. sensor less 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 are also recommended for pumping Argon, but with a longer ramp time to full operating speed.nEXT has been designed to combine all the latest technological advances in turbomolecular pumps with some newthinking in design for manufacture, delivering a truly class leading product.The nEXT platform brings a high level of modularity to offer maximum flexibility for customer application andrequirements. Each pump is available in different internal configurations to offer differing functionality andperformance.On nEXT240, 300, 400 Duplex “D” variants with both turbomolecular and drag stages for improved tolerance to higherbacking line pressures. Triplex “T” variants feature turbomolecular, drag and Edwards unique regenerative pumpingstages for the ultimate in compression ratio and boost technology for unique vacuum system rationalisation.On nEXT85 pumps are available in “D” and “H” variants. The “D” variants offer superior pumping speed andcompression across all gas species. Where an application has a focus on light gas compression, the “H” variant hasbeen physically tuned to offer an improvement in this.nEXT is available in four pumping speeds and a range of inlet flange sizes
