Edwards nEXT240D Turbomolecular Vacuum Pump - NEW
The nEXT240D is a hybrid bearing compound turbo pump available with either an ISO-100 or a CF-100 inlet flange and has a N2 pumping speed of 240 l/s. 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 true user serviceability. They feature 24V to 48 VDC 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 80W or 160W maximum power, the former enabling use with our 100W TIC controllers are also recommended for pumping Argon, but with a longer ramp time to full operating speed. A basic pump system would require a nEXT240D pump, a TAG or TIC controller, either an air or water cooling accessory and a suitable backing pump.
