Absolute Vacuum present the Edwards® EXT406PX compound turbomolecular pump with pumping speeds of up to 34 m3h-1Edwards® EXT406PX compound turbomolecular pump
Edwards® EXT406PX compound turbomolecular pump - Specification- Pumping Speed
- 400 ls-1 (N2) ISO160 & CF160
- 300 ls-1 (N2) ISO100 & CF100
- Vacuum System Simplification
- Capable of operating with a considerably smaller backing pump
- Reduces the footprint and power consumption of the vacuum system
- Can operate at 8 mbar backing pressure with main inlet loaded to 2 E-3
- Can sustain normal operation at backing pressures of up to 17 mbar
- Optional boost port offers up to 24 m3h-1pumping speed at up to 4 mbar pressure
- Ideally suited for use with diaphragm pumps, particularly when using hydrogen
- 24 V DC controller compatible with Edwards TIC Turbo or TIC Turbo & Instrument Controller
- Can also be used with customers own 24 V DC power supply
