Note:
1. The value in the table is obtained under the following condition: ① air pressure is 0.1013Mpa（760mmHg）; ② inlet water temperature is 20℃; ③ relative air humidity is 70％.
2. The value is obtained when the supplied water amount is the suction pressure 0.05Mpa(－400mmHg). It can be bigger than this when it reaches utmost vacuum.
3. The performance difference will not exceed ±10％.
