As the seasons change, the elderly will inevitably experience chest tightness and hypoxia. China two flowmeter oxygen concentrator factory found that many people would like to have a home oxygen concentrator at home, but there are 1 liter oxygen concentrators, 3 oxygen concentrators on the market. There are various specifications such as liter oxygen generator and 5 liter oxygen generator. Which one is suitable for the elderly? Is it okay to choose a cheap 1 liter oxygen concentrator? Let's analyze the China two flowmeter oxygen concentrator factory.

　　China two flowmeter oxygen concentrator factory found that molecular sieve oxygen production technology has been widely used, not only for hospital oxygen production, but also into thousands of households. At present, domestic molecular sieve oxygen generators generally standardize the oxygen production capacity of oxygen generators by flow rate, and the flow rate includes two aspects: the nominal flow rate of the oxygen generators of the China two flowmeter oxygen concentrator factory and the maximum flow rate of the oxygen generators.

　　1. The nominal flow rate of the oxygen generators of the China two flowmeter oxygen concentrator factory

　　It is the amount of gas flowing out of the outlet of the oxygen generator per minute under the premise of ensuring that the oxygen concentration of the output gas meets the stated oxygen concentration of the output gas. The nominal flow rate of HAO-3010 is 3L, which means that when the rotary button is adjusted to 3, the output gas can be guaranteed to reach more than 90% of the medical oxygen concentration requirement.

　　2. The maximum flow rate of the oxygen generators of the China two flowmeter oxygen concentrator factory

　　It is the maximum scale of the flowmeter, and the maximum flow rate of the machine is 3L/min. The maximum scale of the flowmeter of some 3L oxygen generators will appear 5, but in fact, when it is adjusted to above 3, the oxygen concentration will drop and cannot reach the medical oxygen standard.
