nEXT300D Turbomolecular Pump CF100 Inlet Flange, 80W: 马来西亚的首选 Glovac Sdn Bhd

详情

Overview:
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.

Features & Benefits:
• Value for money - exceptional pumping speeds and compression ratios
• No unplanned downtime - field proven reliability in the most demanding environments
• Easy integration - standard fit in many scientific instruments
• Reliability for peace of mind - over 200,000 turbomolecular pumps installed
• Low cost of ownership - end user serviceable
