The oxygen concentration output of 1-7L gear is stabilized at 93%±3%, whether it is 1L/min low-flow regulating oxygen inhalation or 7L/min high-flow emergency oxygen replenishment, the oxygen concentration is always stabilized at 93%±3%, which is as reliable as a sea pin.

Easy to hold with one hand, without the burden. It weighs only 1.45 kg, about the same as three 500 ml bottles of mineral water. It is lightweight and portable, so you can start your healthy oxygenation experience anytime, anywhere. Whether it’s for daily use at home, traveling or business trips, it’s easy to carry around for your respiratory health.

This portable oxygen concentrator features a rechargeable lithium battery that provides oxygen for approximately 4 hours on a single cell. Its versatile power design allows for seamless operation in unpowered environments via a home wall outlet, car power port or battery mode. The removable battery allows for quick replacement during extended outdoor use, while the direct power connection ensures unlimited runtime when plugged in. Ideal for home care, long-distance travel, and outdoor activities, this device provides reliable breathing support around the clock.

Three charging modes:

Lithium battery powered
A/C Wall outlet powered
DC 12V power via car cigarette lighter socket

1-6 gears are pulse mode, through the sensor to detect the user inhalation action, only in the inhalation moment to release oxygen, and stop when exhaling, to reduce the waste of oxygen, and at the same time to improve the oxygen utilization rate (especially suitable for low-flow demand scenarios). 7 gears is a fixed-frequency mode, according to a fixed frequency of oxygen supply, each time to supply the oxygen intensity is the same, and the frequency is not adjusted according to the user’s respiratory rhythm. L is the DC mode, which continuously outputs oxygen with fixed flow rate, no matter the user inhales or exhales, oxygen is always continuously supplied.

The unit operates at less than 45 decibels (dB) and its optimized mechanical and airflow system design ensures smooth, quiet operation. At 1 L operation, the noise level is only about 30 dB – a value that is lower than the ambient sound in a library and far exceeds the industry standard for quietness for similar products. Even when used at night or in confined spaces, it minimizes distractions, making it ideal for continuous oxygen therapy in residential and public spaces.

If the temperature at the exit is too high, the battery is too low, the compressor is abnormal, the gas tank is abnormal, the battery is overheated, the fan is abnormal, the oxygen concentration is too low, and no breathing is detected, the real-time system warning will be activated to protect your family’s safety in all aspects.

The eight-layer filtration is deeply optimized, from primary filtration to intercept large particles of impurities, to medium-efficiency filtration to purify fine dust, and then to high-efficiency filtration to remove extremely small pollutants, with progressive and precise purification. At the same time, for oxygen therapy scenarios, the filter material and structure are specially adapted to ensure that every trace of oxygen is pure, building a solid safety barrier for the oxygen therapy process and providing all-round protection.

You can set the timer from 1 to 99 minutes as you like by clicking the timer button on the screen without having to watch the machine. From now on, oxygen intake is no longer a hassle that requires close attention. You are free to organize your life and have oxygen therapy at the same time! Make oxygen inhalation smarter, less stressful and more personal! Choosing us means choosing a new oxygen inhalation experience that combines quality and convenience!

The oxygen concentrator is fully upgraded with the third generation dual-cylinder compressor, which is a high-performance dual-cylinder low-noise compressor. The double-cylinder structure design, with strong and stable power output, can quickly and continuously provide sufficient power for oxygen production, greatly improving the oxygen output efficiency to meet the oxygen demand of oxygen therapy and other scenarios; at the same time, the materials and processes have been optimized during the R&D and manufacturing process, which effectively reduces the operating noise and creates a quiet environment for use.

This oxygen concentrator is equipped with the core technology of pressure swing adsorption (PSA). Through intelligent pressure regulation and high-efficiency molecular sieve adsorption system, it can quickly separate and purify oxygen and stably output a high-concentration oxygen flow of ≥93%. The technical advantages break through tradition and ensure long-term continuous operation without attenuation. With super adsorption performance and precise voltage stabilization design, it can achieve stable oxygen supply around the clock. Whether it is daily health care or professional care scenarios, it can protect every pure breath with hard-core strength.

This oxygen concentrator comes with a portable shoulder bag, ergonomically designed for comfortable carrying. Whether it’s a long trip around the world, or daily outdoor shopping or strolling on the street, it makes carrying easy and comfortable.

Our oxygen concentrator is equipped with a 2.8-inch high-definition large screen and uses backlit LCD display technology. Even in a dimly lit bedroom or at night, it can clearly display key data such as oxygen concentration and oxygen supply, preventing misoperation due to blurred vision. The operation area uses large physical buttons with raised surfaces and non-slip textures, which are clear to the touch and easy to locate. The elderly can also easily adjust the oxygen flow and turn the machine on and off with one button.

The oxygen directly output by the oxygen concentrator is relatively dry. This machine is equipped with a humidification bottle, so that the oxygen passes through the pure water in the humidification bottle before entering the human body, carrying a certain amount of moisture, so that the inhaled oxygen is closer to the humidity of the normal physiological environment of the human respiratory tract, effectively protecting the respiratory mucosa and maintaining its normal physiological function.

In terms of structural design, the oxygen concentrator adopts a three-dimensional surround heat dissipation channel, and precise heat dissipation holes are densely distributed on the side of the fuselage to form efficient air convection. During operation, air flows in, takes away the heat through the internal heat conduction structure, and then is discharged from the side heat dissipation port, which quickly improves the heat dissipation efficiency. Excellent heat dissipation performance brings significant advantages: first, it extends the service life of the equipment and saves maintenance costs; second, it ensures that the oxygen concentrator can still stably output 93% oxygen concentration and run smoothly without attenuation even in high-intensity scenarios such as 24-hour continuous oxygen therapy and all-day outdoor use; third, the fuselage always maintains low temperature operation, which is safe and worry-free to use in small spaces such as public transportation.

There is a battery release button in the middle of the bottom. Press it and pull it parallel to the front of the host to remove the battery for easy replacement.
