Larger Flow

Portable Oxygen Concentrator


50% Larger Flow

SG adopts the newest pulse flow design. It can deliver a 50% larger oxygen flow than the old POC. SG can better meet the higher oxygen demand of outside activities.

Full of Vitality

With a larger oxygen supply, we are capable of more daily activities with less effort. Relaxed travel and more exercise could help us get a better lung recovery and a higher quality of life.

Why need a larger flow outside?

The oxygen demand varies in different activities. It will increase from 20% to 50% higher than sitting quietly at home.

However, the old portable oxygen machine delivers oxygen based on sitting quietly at home, which will cause silent hypoxia. It will damage our organs and limit our activity ability as time goes by.

Oxygen Flow Chart

Oxygen Concentration: 90% + 5% / - 3% at all settings (Medical Grade)

The old-generation portable oxygen machine delivers an average of 210 milliliters per gear.

The new-generation portable oxygen concentrator delivers an average of 330 milliliters per gear.

The new device delivers 50% more oxygen at each flow gear.

Temporary emergency response

In emergency situations, it will activate an extra 20% oxygen production capacity to guarantee enough oxygen supply. But it will shorten the lifespan of the device.

It's prepared for unexpected situations. Please do not activate it in non-emergency situations.

Safety with a Larger Oxygen Flow POC

With a larger oxygen supply, no matter whether at home or outside, we can get enough oxygen. we no longer need to worry about the invisible hypoxia caused by increased activity outside.

With a larger oxygen flow POC, keep our health at safety all the time.

Besides, we can view our breath conditions, oxygen supply, and battery remaining time to arrange our schedule freely.

No matter whether we are in a wheelchair or on the bed or anywhere in the house, everything will be simple by just touching the phone.

Invisible Sunglasses Nasal Cannula (Optional)

No Tubes on Our Face

By wearing sunglasses nasal cannula, there will be no more tubes on our faces. It effectively solved the friction between the oxygen tube and the face and ear during long-term oxygen therapy.

Just go anywhere you want to go.
