With an unabated increase in oxygen demand in such high polluted environmental surroundings, oxygen concentrators like the Yuwell 8F-5A are the best thing to rely on. Unlike the other medical oxygen devices like oxygen cylinders, the Yuwell 8F-5A oxygen concentrator has the advantage of being operational 24/7 with easy access even at the convenience of your home. The Yuwell 8F-5A concentrator is capable of maintaining a flow rate between 0 to 5 LPM. This is quite sufficient to be an ideal choice for portable use. Along with this, the output discharge pressure for the oxygen is in the range of 40-70 KPA, which ensures that the patient will get the required oxygen quickly and without any delay.
