Note:
① The performances in the table refers to air temperature at 20 ℃, atmospheric pressure at 1013.25hpa (760 mmHg), relative humidity of air at 70% and temperature of circulating water at 15℃.
② Tolerance of air pumping rate at ± 10%.
③ The readings of the degree of vacuum in the table refer to the pressure below standard atmospheric pressure. (1 mmHg = 1 Torr = 133.3 Pa, 0.1 Mpa = 750 mmHg)
