Main technical specifications
1. Recommended maximum oxygen flow: 5L/min.
2. Flow scope when the nominal pressure at the outlet is 7kPa:
0.5L/min～5L/min.
3. Apply 7kPa back pressure at the recommended maximum
flow, the flow reaches accuracy of ± 10% to the indicated flow.
4. Oxygen concentration when the nominal pressure at the
output is zero (achieve the required oxygen concentration level
within 30 minutes of the initial startup): the oxygen yield is
0.5L/min to 3L/min, the oxygen concentration is ≥90%.
5. Output pressure: 0.02MPa～0.07MPa
6. See Figure 1 for function table of oxygen concentration and
oxygen flow when the nominal pressure at the output is zero.
7. Release pressure of compressor’s safety valve: 280kPa±50kPa
8. Noise: ≤ 60dB(A)
9. Maximum nebulization rate: ≥ 0.1mL / min (for model with nebulizer)
10. Power supply voltage: 220V±22V/110V±11V, 50Hz/60Hz ±1Hz
11. Input power: 450VA
12. Net weight: 17.42 kg
13. Dimensions: 38.5×25×44(cm)
14. Altitude: the oxygen concentration will not be reduced when it is from sea level to 1828m, but
the oxygen concentration will be less than 90% when it is from 1828m to 4000m
15. Safety system:
▲ Shutdown due to current overload or loose connections
▲ Shutdown due to high temperature of compressor;
▲ Low oxygen concentration alarm;
16. Shortest working hours: not less than 30 minutes.
17. Electrical classification: Class II equipment, type B application part
18. Running mode: continuous operation
19. Normal working environment
▲ Ambient temperature range: 5 ℃ to 40 ℃;
▲ Relative humidity range: ≤ 80%;
▲ Atmospheric pressure range: 860hPa to 1060hPa.
Notice: When the storage and transportation temperature is below 5℃, the oxygen concentrator shall
be placed in normal working temperature for more than 4 hours before operation.
20. Oxygen outlet temperature: ≤ 46℃
21. Suggestion: the length of the oxygen tube shall not exceed 6 meters, and the oxygen tube can not
be bent or deflated.
22. Storage and transportation environment:
▲ Ambient temperature range: -40℃～+70 ℃;
▲ Relative humidity range: 10% to 100%, and no condensation;
▲ Atmospheric pressure range: 860hPa to 1060hPa.
Notice: The oxygen concentrator shall be stored inside the room where there is no strong sunlight,
no corrosive gases but well ventilated. Do not shake or place upside down the oxygen concentrator
during transportation.
