Here’s how it works:

1. Air intake: The concentrator draws in air from the surrounding environment through an intake filter.
2. Compression: A compressor compresses the air to increase its pressure.
3. Filtration: The compressed air passes through a series of filters that remove nitrogen, water vapour, and other impurities.
4. Separation: The filtered air is then passed through a zeolite molecular sieve, which selectively removes nitrogen and traps it within it.
5. Concentration: The remaining air, which is now enriched with oxygen, is delivered to the patient through a nasal cannula or another delivery device.
6. Waste removal: The nitrogen removed from the air is expelled to the surrounding environment.

An oxygen concentrator operates continuously and provides a constant flow of oxygen, making it an effective and convenient solution for people who require supplemental oxygen for medical conditions such as chronic obstructive pulmonary disease (COPD), emphysema, and pneumonia.
