GVS Portable Oxygen Concentrator 5 Ltr Review

The oxygen concentrator by GVS helps alleviate cardiovascular disorders. It brings relief to people suffering from respiratory diseases like chronic obstructive pulmonary disease. It is needed for people with physiological hypoxia. It is also useful for patients whose blood oxygen levels are abnormally low in the natural state.

The machine increases the physical supply of oxygen, thus increasing the amount of oxygen available for absorption by the blood. It is suitable for use by middle-aged and elderly people, and pregnant women. It can be used to reduce fatigue and restore somatic functions after doing strenuous activity.

The gadget is based on Pressure Swing Adsorption technology. It uses a super-absorbent molecular sieve to separate oxygen from nitrogen at room temperature. It produces oxygen with a purity level of 93% ±3%. The device has France CECA sieve analysis. It has a flow rate of 0-5 liters per minute. It features a 4-stage filtration system and it does not use additives.

The concentrator needs a constant power supply. It starts producing oxygen within 2 minutes of powering up. It is quick to start, simple to use and consumes very less electricity.

Here’s how you can use the GVS oxygen generator. First, fill the humidifier bottle with clean water. For this you need to remove the silicone rubber tube from the bottle, fill water to a level between the minimum and maximum lines, close the cap, place the bottle in the transparent cover and insert the silicone rubber tube. Then, press the power button and then the Oxygen Timing button. You can preset the operation time up to 120 minutes. The default preset time is 30 minutes. To increase the time, you need to press the Oxygen Timing button. For every press, the timing goes up by 30 minutes until it hits 120. The device stops after the preset time elapses. If you need it for more than 120 minutes, you need to repeat the process once the first 120 minutes are over. You can also adjust the flow of the oxygen by turning the Flow Control knob.

The machine has a plastic housing. It contains the motor, a humidifier bottle, a heat exchanger, oxygen tubes, a flow meter, primary air suction filtering sponges and secondary air suction filter. It has small lights to indicate the status of operation. If everything is normal, the Power, Purity and Trouble lights stay green.

The device comes with a carry bag that lets you carry it on your shoulders. It has multiple pockets, a long strap with a shoulder pad and a short handle on top. There is a cut-out in front to show the display screen and the control panel.

The device also includes a cart with wheels and a collapsible telescopic handle so that you can carry it around like a suitcase or a trolley bag. The idea is that it should be able to accompany the patient wherever they go, whether they are at home or outside. The device should be travel-friendly and suitable for use in cars, trains, planes, parks and other public places. This can go a long way in helping the patient lead a normal life.

There are 2 ways to power the oxygen concentrator: direct power from a wall receptacle or a battery. The integrated rechargeable battery offers a back-up of up to 2 hours. You need to recharge the battery when it starts to dip. It takes 4 to 5 hours to be fully charged. While traveling by car, you can power the machine through your car battery too. An AC power supply cable, a car inverter, a battery power and a battery charger are included in the package.

The oxygen machine has a long lifespan of 10,000 hours. It has whisper-quiet operation and seldom exceeds 45 dB. The back-lit liquid crystal display screen shows the total working hours. You can set the oxygen absorption time as per your requirement. Once the preset oxygen concentration time is reached, the device shuts down automatically. In case of power failure or low voltage (less than 190 V ± 10 V, or 95 V ± 5 V), the device sounds an alarm and stops working. The Trouble light turns red and you can only restart the machine when the power is back on or when the voltage returns to normal. The oxygen concentrator sounds an alarm and the Trouble light goes red if the oxygen circulating pressure is too high or too low. You also hear the alarm if the oxygen purity level falls below the acceptable level or if there is a short circuit in the air compressor.

The appliance comes with a remote control that has a range of 10 meters. Dimensions of the device are: 49 cm by 27 cm by 56 cm. It weighs 22 kg without the battery. The machine is designed to work at a maximum altitude of 12,000 feet and a humidity level of 15 to 95%. Voltage is AC 220 V±22 V, 50 Hz±1 Hz /AC 110 V±15 V, 60 Hz±1 Hz. Atomization is ≥0.15 ml /min.

The product has a warranty period of 24 months or 5000 hours, whichever is earlier, from the date of purchase.
