Is the oxygen produced by industrial oxygen generators the same as that from oxygen cylinders?
First of all, it is certain that the oxygen from oxygen generators and oxygen cylinders is essentially the same. The oxygen concentration of oxygen generators is generally above 90%, while that of oxygen cylinders exceeds 99%. In terms of concentration, oxygen in cylinders is purer.
Short-term oxygen inhalation: Oxygen cylinders are recommended
Generally speaking, oxygen cylinders are a better choice for temporary short-term oxygen therapy. They feature high oxygen concentration, large adjustable flow rate and quiet operation.
The oxygen inside cylinders is filled under high pressure at refueling stations, which ensures high internal pressure and allows users to set a relatively high oxygen flow.
Another major advantage of oxygen cylinders is low noise. They produce no extra sound during oxygen supply, so they will hardly disturb patients’ rest.
However, oxygen cylinders also have drawbacks. The biggest inconvenience is frequent replacement and refilling. It is particularly troublesome for users living in remote areas. If the patient needs large oxygen intake, 2 to 3 cylinders may be consumed per day, causing much hassle.
Long-term use: Industrial oxygen concentrators are preferred
For use lasting more than half a year, industrial oxygen concentrators are highly recommended for lower long-term costs and greater convenience.
Oxygen concentrators generate oxygen by internal zeolite molecular sieves, which separate nitrogen from ambient air, leaving oxygen and trace rare gases.
The core advantage is unlimited oxygen supply. As long as the machine works normally, continuous oxygen is available without frequent cylinder replacement and refilling. It is much more cost-effective in the long run. A 3-liter oxygen concentrator costs around 3,000 yuan, and it will be more economical than oxygen cylinders if used for over six months.
