Oxygen concentrator is a machine that produces oxygen. The principle is to use air separation technology. First, the air is compressed with high density, and then to separate the gas from liquid at a certain temperature due to their different condensation point, and next it is separated into oxygen and nitrogen by rectification technology. It is a O2 supply machine which mostly used to produce oxygen, so people call it oxygen concentrator.
