1. The power supply of this adapter atomizer is AC220V/50HZ, which can provide stable power supply and ensure the normal operation of the atomizer. 2. The electrical input power is 18VA, which can quickly start the nebulizer, accelerate drug nebulization and reduce waste. 3. The output gas flow rate is greater than 5L/min, which can ensure uniform and rapid drug atomization and improve drug efficacy. 4. Under normal working conditions, the nebulizer can generate a pressure of 40KPA ~ 80KPA, which can atomize the drug into particles evenly and quickly to improve the efficacy of the drug. 5. The working noise of the whole machine does not exceed 50dB(A). It is very quiet during the working process and will not cause interference to users. 6. The residual volume is less than 0.8mL, which indicates that the nebulizer can improve the degree of nebulization of the drug, and avoid waste while exerting the drug effect. 7. The atomization rate is greater than 0.2mL/min, indicating that the drug is atomized evenly and quickly, which can better improve the efficacy of the drug. 8. The median particle size is 0.35um25%, indicating that the drug atomized particles are uniform in size and can effectively reach all parts of the respiratory system. 9. Under normal working conditions, it is suitable for places where the ambient temperature is 10C to 40C, the relative humidity is 30% to 80%, and the atmospheric pressure is 70.0KPA to 106.0KPA. It can work stably and safely. 10. The size of the whole machine is 157x98x96mm, small in size, easy to carry and store, suitable for home and travel use.
