The Basic Design and Components

An oxygen concentrator has a simple design, typically consisting of an air compressor, sieve bed filters, and a pressure swing adsorption (PSA) system. The compressor compresses the ambient air and passes it through the sieve bed, which separates the nitrogen and other gases from the oxygen to produce medical-grade oxygen. The oxygen is then stored in a tank or delivered directly through a nasal cannula or face mask.

How the PSA System Works

To understand how the PSA system works in an oxygen concentrator, we need to start by understanding what it is. The PSA system is a process of separating gases based on their molecular weight and size. In the case of an oxygen concentrator, it’s used to extract the oxygen from the ambient air.

The process starts when the compressed air is pushed into the PSA system through a valve. Inside the PSA system, there are sieve beds filled with adsorbent material, in most cases, zeolite molecular sieves. The adsorbent material has a high affinity for nitrogen, which makes it bind to the surface of the sieve material, leaving the oxygen and other gases free to pass through.

As the compressed air passes through the sieve beds, it’s exposed to alternating high and low pressures, a process called pressure swing adsorption. This technique helps to extract more oxygen from the air by forcing it through the adsorbent material in the sieve bed.

The Importance of Proper Maintenance

Like any other medical device, an oxygen concentrator requires proper maintenance to function effectively. As these devices are used to provide life-sustaining oxygen, it’s vital to ensure that they’re working correctly.
