Power supply: AC220V50Hz Machine noise: 70dB (A-weighting) Power adapter: 12V Output power: 20VA Atomization rate: >0.2mL/min Residual liquid volume: 2mL Gas flow: 5L/min Bodyweight: Approximately 255 g Under normal working conditions, the maximum pressure generated by the atomizer should be in the range of 60kPa- 130kPa. When the host is abnormal, the maximum pressure generated by the atomizer should be in the range of 150kPa- 400kPa, and the tube body should not be ruptured. Equivalent volume particle size distribution: the proportion of fog particles 55% Median particle: The median particle size of the fog particles is 2.5um, and the error should not exceed ±25%
