Power supply: AC220V±22V, 50Hz±1Hz

Rated power: 320W

Noise: <54dB (A)

Flow range: 1-3L/min

Oxygen concentration: 1-3L/min≥90%

Maximum output pressure: 60KPa±6KPa

Compressor relief valve pressure (pressure protection):250KPa±25KPa

Flow fluctuation (at 7KPa back pressure): 0.7L/min

Atomization amount: ≥0.2mL/min

Continuous running time: 24 hours/day

Current overload protection switch: 5A, 220V

Weight: 22Kg

Use environment temperature: 5℃~40℃

Relative humidity range: ≤80%

Atmospheric pressure range: 86KPa~106KPa

Oxygen concentration status indicator (OCSI) operatingtemperature and atmospheric pressure range: 0~50℃; 150KPa

The oxygen concentration status indicator prompts theoxygen concentration value when the oxygen concentration is abnormal: <82%±1.8% (80.5%~83.5%)

Operating altitude: above sea level, it can be usednormally in the environment below the altitude of 1828 meters. It is notrecommended to use it at an altitude higher than 1828 meters. From an altitudeof 1828 meters to an altitude of 4000 meters, the efficiency of the machine isless than 90%, and the oxygen concentration decreases as the flow rateincreases.
