Oxygen making principle:
This equipment uses ~ 110V power source as the power source, air as the raw material, high-quality and efficient molecular sieve, and PSA method at normal temperature to produce high-purity oxygen that meets medical standards and can continuously supply oxygen.

1. Maximum recommended flow: 10L / min
2. Flow range at nominal outlet pressure of 7kPa: 0.5 ~ 10L / min
3. When a back pressure of 7kPa is applied, the maximum recommended flow change should be
within ± 10% of the specified value.
4. Oxygen concentration value when the outlet nominal pressure is zero (30 minutes after initial start-up, the specified oxygen concentration level is reached): When the oxygen flow rate is 0.5 ~9L / min, the oxygen concentration is> 90 (V / V)%.
5. Output pressure: 58kPa ± 5kPa.
6. when the nominal outlet pressure is zero, the oxygen concentration and oxygen flow
7. Compressor safety valve release pressure: 250kPa ± 50kPa
8. Machine noise: ≤60dB (A)
9. Power supply: ~ 110V ± 10V, 50Hz ± 1Hz
10. Input power: 580W
11. Net weight: 23kg
12. Dimensions: 43 × 38 × 72 (cm)
13. Altitude: When the sea level reaches 1828 meters, the oxygen concentration will not be reduced.Efficiency is less than 90% from 1828 meters to 4000 meters.
14. Electrical classification: Class Ⅱ equipment, type B application part
15. Working system: continuous operation
16. Normal working environment:
◊Ambient temperature range: 5 ℃ ~ 40 ℃ ;
◊Relative humidity range: ≤80%;
◊Atmospheric pressure range: 86kPa ~ 106kPa
When the storage and transportation temperature is lower than 5 ℃ , the equipment should be in normal condition before use.
Leave in the working temperature environment for more than four hours.
17. Oxygen outlet temperature: not more than 6 ℃ above ambient temperature.
18. Atomization function
Atomization rate: ≥0.2mL / min
Residual liquid volume: the atomization is over, the liquid in the atomization cup is lower than 2mL
19. Recommendation: The length of the nasal tube cannot exceed 15.2 meters, and it cannot be folded.
20. Security system:Low oxygen flow and low oxygen concentration alarm;
Current overload shutdown, wire disconnection or power failure alarm;
The compressor is shut down at high temperature, and the system pressure is automatically released when the pressure is overloaded.
Package Includes:
Oxygen concentraror * 1
Humidifier bottle 1 Set
