FAQ 1. What is the purpose of oxygen concentrator? Oxygen concentrators are used by people with chronic breathing problems or chronic obstructive pulmonary disease(COPD). COPD includes bronchitis, emphysema and even severe asthma.In basic terms, oxygen concentrators provide a more concentrated flow of oxygen than a user can get in the surrounding ambient air. 2. What is the working principle of oxygen concentrator? The concentrator accomplishes this by pulling regular air into a chamber within the concentrator. The chamber absorbs the nitrogen which is vented out back into the ambient air while the oxygen flows to the user. Since the remaining oxygen is very nearly pure, it can be more easily taken into the bloodstream, which puts less strain on the heart. 3. What is your after-sales service policy?
