| Feature | Specification | ||
Product name | Oxygen Concentrator | ||
Model | KF08-5YW | ||
Rated voltage and frequency | AC220-240V, 50Hz | ||
Mode of operation | Continuous duty | ||
Rated input power | 450VA | ||
Noise level (average) | ≤ 60 dB (A) at 5 L/min; | ||
Alarm sound volume | ≥ 62 dB（A） | ||
Altitude | It can be used normally in environments below 1828 m above sea level. It is not recommended for use at altitudes higher than 1828 m. Oxygen flow and concentration will be significantly compromised at altitudes above 1828 m. | ||
Physical and chemical parameters of output oxygen | *The claimed oxygen concentration level (93% ± 3%) (V/V) can be obtained after a certain period of warm-up (approximately 30 min after power-on). Carbon dioxide content: ≤ 0.01% (V/V) Carbon monoxide content: ≤ 0.0005% (V/V) Particle size of solid substance: ≤ 10 μm Solid substance content: ≤ 0.5 mg/m³ | ||
Maximum output pressure | ≤ 70 kPa | ||
Flow range | 0.6-5 L/min | ||
Flow accuracy | The flow should be ± 10% of the indicated value or ± 200 mL/min at the back pressure of 0 kPa and 7 kPa, whichever is greater. | ||
Low flow alert | There is an alert in sharp beeps when the flow is below 0.6 L/min (when no accessories are connected to the device). | ||
Maximum system allowable pressure (Pressure protection) | 241 ± 24.1 kPa | ||
Flow fluctuation (at the back pressure of 7 kPa) | < 0.6 L/min | ||
Circuit breaker | F6.3AH250V | ||
Filters | Oxygen outlet filter and compressor inlet filter | ||
Safety system | Oxygen concentration/flow displayCompressor error alarmCompressor high temperature protectionCirculation pressure fault alarmLow oxygen concentration alarmSystem communication fault alarmLow supply voltage alarm Temperature error alarmPower outage alarmNo-breathing alarmLow flow alertLow oxygen concentration alert | ||
IP rating | IP21: solid object ingress protection level 2, water ingress protection level 1 | ||
Size | 42 (L) *28(W) *55(H)CM | ||
Weight | 16.35kg | ||
Operating environment | Temperature: 5℃ ～ 40℃ Relative humidity: ≤80% Atmospheric pressure: 81kPa-106kPa | ||
Exhaust air temperature | No higher than 75°C | ||
Output oxygen temperature | No higher than 45°C Note: Under the specified environmental and operational conditions, the temperature in question is considered safe for prolonged oxygen administration to patients via a nasal cannula, posing no risk of burns or thermal damage. Oxygen undergoes rapid cooling as it flows through the catheter and mixes with ambient air. The actual temperature of oxygen perceived within the patient's nasal cavity will not be significantly higher than the ambient temperature. | ||
Electricity | No extended power cord | ||
Main components and structure | The product consists of a filtration system, a compressor, left and right sieve canister assemblies, a circuit control system, a noise reduction system, pulse oxygen delivery system, electronic flow regulation system, intelligent voice system, embedded software (release version No.: ZY004), a humidifier bottle, and connecting tubing. | ||
Placement | No less than 7.5 cm away from a wall, furniture, tapestry or similar object. | ||
Continuous operation time per day | 24h | ||
Storage and transportation environment | Temperature: -20℃ ～ 55℃ Relative humidity: ≤93% Atmospheric pressure: 81kPa-106kPa | ||
Manufacturing date | See the outer packaging | ||
Service life/ Shelf life | 5 years | ||
Type BF applied part | Nasal cannula | ||
| Indicator Light | |||
State | Indicator LED (diode) | ||
Alert | Red LED | ||
Alarm | Yellow LED | ||
Normal operation | Green LED | ||
| Circuit Breaker | |||
686Series 125/250VAC/50VDC F6.3AH250V | When the input current of the oxygen concentrator exceeds the rated current of the circuit breaker, the circuit breaker will be automatically deactivated for protection in case of electric shock, and the oxygen concentrator will stop working. When the user excludes abnormal power supply, just press the button on the top of the circuit breaker, and the circuit breaker can resume working | ||
