The pump has a pair of rotors that are designed and processed with good symmetry, so it features high speed, small size, light weight, and reduced vibration. It has a compact structure and a small footprint.
- Quick Start can reach the ultimate vacuum in a short time. No compression occurs in the pump cavity so condensable gases can be eliminated without a vent valve.
- The gaps between the rotors and the pump cavity ensure no friction and low power consumption, and the benefit of energy-saving.
- Requires no oil lubrication
- Stable pumping speed within the pressure range of 1.3 x 103 ~ 1.2Pa
- Relief valve for automatic overload prevention
