How oxygen concentrators work

How oxygen concentrators work?

Oxygen concentrators typically use pressure swing adsorption (PSA) technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or in remote clinics & hospitals. For other purposes there are also concentrators based on membrane technology.


An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. Oxygen concentrators are also used to provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generating systems. Oxygen concentrators utilize a molecular sieve to adsorb gases and operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals and then venting the nitrogen. This type of adsorption system is therefore functionally a nitrogen scrubber leaving the other atmospheric gases to pass through. This leaves oxygen as the primary gas remaining. PSA technology is an incredibly reliable and economical technique for oxygen production, with cryogenic separation more suitable at higher volumes and external delivery generally more suitable for small volumes.

Oxygen on demand

In today’s connected and technologically driven world, its hard to believe that many organizations still struggle with Oxygen supply.  What it comes down to in most cases is the reliance on third party suppliers, which despite promises, can’t always deliver. For companies operating in Africa, another major factor in oxygen supply is also site location. Many locations are remote and surrounded by poor infrastructure which makes it incredibly difficult for gas suppliers to deliver and maintain that supply, and if they can it comes at a very high cost.

The uses for oxygen range from increasing gold recovery in the mining sector, improving fish stocks in Aquaculture right through to critical life support systems in the Medical sector.

Oxygen on demand

What many organizations don’t realize is that it is possible for them to take control of their oxygen supply by producing their own. Our systems are custom designed from the ground up and take into account all the customer requirements. Everything is considered and we work carefully to ensure the system matches the application. System size, location, available space, environmental factors (temperature, humidity and altitude), layout, material considerations, shipping/freight etc are all carefully considered.

Comprehensive training and support forms part of the offering too, regardless of Country. We currently have systems throughout Africa including countries such as Liberia and Sierra Leone which were recently devastated by Ebola as well as Rwanda and Mali which suffered many years of political unrest and civil war.

If you find yourself struggling with your oxygen supply, take the first step by contacting us and lets see what we can do to help.
