An oxygen concentrator is a device that concentrates oxygen from the air by filtering out nitrogen and other gases. Oxygen concentrators are mainly used for patients with respiratory problems, or for people who need additional oxygen for a long period of time.
Oxygen concentrators machine work based on the principle of Pressure Swing Absorption (PSA), which involves the separation of gas species from a mixture of gases under suitable pressure. Based on this principle, oxygen concentrators use zeolite particles for the separation of gases. At high pressure, zeolite particles adsorb large particles such as nitrogen, and oxygen is compressed and moved to the other end of the valve.
This process of separation takes place in two adjacent sieve beds, with a cycle time of 10 seconds. Zeolite is used to filter water in these sieve beds. Through one end of the valve, oxygen is collected while nitrogen is removed.
The HEPA filter and Cabinet filter used in these machines are capable of filtering large and small particles to a great extent. Oxygen concentrator machines are a replacement for oxygen cylinders. since these machines only need electricity to work, and do not need to be refilled at all. If you need supplemental oxygen at home, one option is to get a portable oxygen machine. This type of machine is small and can be easily moved from room to room, so you can always have it close by.
