An oxygen concentrator is a type of medical device used for delivering oxygen to individuals with breathing-related disorders. Individuals whose oxygen concentration in their blood is lower than normal often require an oxygen concentrator to replace that oxygen.

The oxygen concentrator is designed to produce and extract oxygen, which adopting air separation technology. Firstly, the air is compressed with a high density, and then using different condensation points of each component in the air, so that the air is separated by gas and liquid at a certain temperature, finally it would be further rectified to get oxygen. Designed to meet the demands of active patients, this compact size oxygen concentrator delivers effective oxygen therapy in a portable package.
