The molecular sieve dosage and compressor performance of the 3-liter machine and the 5l oxygen concentrator are different, and the work load they can bear is different.

Generally speaking, a 5l oxygen concentrator contains more molecular sieve than a 3-liter oxygen concentrator. At the same time, its power components are also the main cost. The air compressor in the oxygen concentrator can withstand more workloads. . It is more suitable for people who need long-term oxygen therapy every day. For example, for people with COPD, they should use 5l oxygen concentrator more than 3l oxygen concentrator.

In terms of oxygen flow, people with COPD should adopt low flow: 1.5 to 2.5 liters of oxygen per minute for oxygen therapy. This will make some people think that only 3 liters of oxygen concentrators are enough. However, when inhaling oxygen In terms of time, for people like COPD, the daily oxygen therapy time is relatively long. They are often advised that the daily oxygen therapy time should not be less than 15 hours, and if allowed, it is better to 24 Oxygen inhalation for hours.

The 3 liter oxygen concentrator is driven at 1.5~2.5 liters per minute. The air compressor on the 3 liter machine has carried a certain workload, and then it will work for a long time for 15 hours or 24 hours, which makes the life of the compressor A sharp drop can easily lead to machine failures.

5l oxygen concentrator, many companies have designed a 5-liter oxygen concentrator as a 24-hour operation mechanism. The compressor displacement is larger, the heat dissipation performance is better, and the performance is stronger. When 1.5~2.5 liters are selected, because The 5l oxygen concentrator has a larger displacement, more margin, and is in a lower load state. Although the displacement of the 5l oxygen concentrator is attenuated during long-term operation, it can also meet the minimum requirements of the system. Longer life. For COPD people, this oxygen inhalation mode is more secure and appropriate.
