A. Structural features:
The product structure consists of an oxygen generator, a flow meter, a humidifier, and an atomizing interface assembly (only applicable to JMC9A Ni, JMC9B Ni models).
The accumulated timer can display the total running time of the equipment.
System operation fault detection, including pressure, low oxygen concentration, and low oxygen flow.
Compressor air pressure overpressure safety valve, to better ensure the safety of the compressor and the entire machine.
Equipped with power failure alarm function and over current protector.
Sleeve-type housing design, convenient maintenance and good noise shielding effect.

B. 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: 9L / min
2. Flow range at nominal outlet pressure of 7kPa: 0.5 ~ 9L / 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
