Pressure Swing Adsorption Specialists

Pressure Swing Adsorption Solutions
Pressure Swing Adsorption (PSA) is a widely used technology for separating gases from a mixture of gases under pressure according to the species’ molecular characteristics and affinity for an adsorbent material. Under high pressure, gases tend to be attracted to solid surfaces, or adsorbed.
To produce oxygen and/or nitrogen on site, it involves the separation of air, a free raw material, into these separate gases

Reduced OPEX
No set cost per quantity but cost per unit reduces with time and volume.

Improved ESG
On-Site Production removes the need for freight.

Constant & Reliable Supply
Removed need for 3rd party producers & delivery.

Oxygen/Nitrogen Availability
Access to oxygen and nitrogen in remote areas.
Affordable On-Site Gas Production Solutions
Inflation, rising logistics prices & increased carbon emissions are making traditional centralized gas production solutions unfeasible and unattractive across multiple industries.
Each year, more than 3 million Africans die of conditions where medical oxygen is an essential treatment.
Inflation & transport are driving up food prices across Africa, with an urgent need to drive down input costs.
Recycling steel can reduce energy consumption by up to 70% compared to producing new steel from iron ore.
High demand for Industrial & Gold Mining bulk oxygen supply increases our carbon emissions from freight.
Carbon emissions are causing increased global temperatures and climate change. Companies need to take an increased focus on their ESG.
Aquaculture is a sustainable practice to reduce overfishing and increase food supply for a growing global population.
What is Pressure Swing Adsorption Technology?
O₂Africa is a specialist in using Pressure Swing Adsorption for On-Site Oxygen & Nitrogen gas generation throughout Sub-Saharan Africa.

Experts In Gas Generation
At O₂Africa, we are experts in Pressure Swing Adsorption (PSA) technology, excelling in the production of high-purity oxygen and nitrogen from air. Utilizing a well-established method, our PSA systems for oxygen production feature two columns filled with Zeolite, while our nitrogen production systems employ Carbon Molecular Sieve (CMS) as the adsorbent material.
The adsorption process selectively separates the gases, allowing oxygen-enriched air for oxygen production and nitrogen-enriched air for nitrogen production. With precision and efficiency, our PSA systems continuously alternate between adsorption and desorption phases, ensuring a consistent supply of high-quality gases.

A Safer, Smarter Way to Protect Your Grain: The Power of Nitrogen Storage
South Africa’s grain producers are embracing nitrogen-controlled atmosphere storage as a safer, cleaner, and more sustainable way to protect their harvests. Using advanced Pressure Swing Adsorption (PSA) technology, this method replaces oxygen with nitrogen to create a pest-free, chemical-free environment that maintains grain quality, extends shelf life, and supports food safety compliance. From maize and wheat to soybeans and rice, nitrogen storage is proving to be a reliable and cost-effective solution that protects both people and the planet.

Breathing Life into Aquaculture: Why Oxygen Matters More Than You Think
Aquaculture is growing fast across Africa, but every farm depends on one invisible ingredient: oxygen. From tilapia in Zambia to salmon in Norway, dissolved oxygen determines growth, survival, and profitability. Traditionally, many farms have relied on oxygen cylinders, but unpredictable deliveries and high costs limit progress. Pressure Swing Adsorption (PSA) technology is changing that story by providing reliable, on-site oxygen generation. Discover how farms from Botswana to Vietnam are using PSA systems to cut costs, improve fish health, and build a more sustainable future for aquaculture.

Packaging That Performs: Nitrogen Flushing the Smart Way
Nitrogen flushing is a smart, cost-effective way to extend food shelf life and preserve quality. Learn how onsite PSA nitrogen systems from O₂Africa are helping South African food producers stay fresher, longer – without relying on gas deliveries.
