Power supply: AC220V±22V, 50Hz±1Hz
Maximum output pressure: 45KPa±4.5KPa
Compressor relief valve pressure (pressure protection):250KPa±25KPa
Flow fluctuation (at 7KPa back pressure): 0.7L/min
Continuous running time: 24 hours/day
Current overload protection switch: 5A, 220V
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℃;
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.
