The report includes an in-depth analysis of the Global Pressure Swing Adsorption Units Market, including market size and trends, product mix, Applications, and supplier analysis. The global Pressure Swing Adsorption Units Market was valued at USD 2.7 billion in 2024 and is expected to grow at a CAGR of over 7.04% from 2025 to 2034. The adoption of PSA (Pressure Swing Adsorption) units has grown steadily, driven by their ability to enhance gas purity and support unit efficiency. Early investments in PSA technology highlight its shift toward greener solutions for gas separation. Technological advancements—such as improved system designs and advanced adsorption materials—have created new market opportunities. There is rising demand for compact, portable PSA systems suitable for smaller or remote applications. These mobile units are gaining popularity, particularly in the healthcare sector and for on-site gas generation, where flexibility and efficiency are essential.

The pressure swing adsorption (PSA) units market is segmented based on gas type, with the oxygen segment currently dominating. This dominance is largely due to the growing demand for oxygen in the healthcare sector, where hospitals and clinics increasingly adopt PSA systems for on-site oxygen supply to avoid delays during emergencies. The rise in respiratory illnesses, especially among the aging population, continues to drive this trend. Additionally, the urgent need for reliable oxygen supply during the Covid-19 pandemic significantly accelerated investment in PSA technology, further strengthening the oxygen segment’s leading position. The gas separation segment holds a significant share of the PSA units market and is experiencing steady growth. This is largely driven by rising demand for industrial gases in sectors such as chemicals, petrochemicals, and manufacturing. PSA technology’s cost and operational efficiency make it ideal for separating gases like nitrogen, oxygen, and hydrogen. On-site gas generation using PSA units reduces reliance on external suppliers, boosting segment growth. Additionally, the push for cleaner energy and lower carbon emissions is increasing PSA adoption in gas separation processes, promoting energy efficiency and sustainability across industries.

The U.S. dominates the pressure swing adsorption (PSA) units market in North America, driven by strong demand from industries such as chemicals, oil and gas, and food and beverages. Its advanced industrial infrastructure and push for cleaner energy support PSA growth, especially for on-site oxygen generation in healthcare and renewable energy applications like hydrogen production and biogas upgrading. In Canada, the PSA market is expanding due to government incentives promoting sustainable energy and increased healthcare demand for oxygen systems. In the Asia Pacific region, rapid industrialization—especially in China—fuels market growth, with China leading the region due to rising consumption of industrial gases and a national focus on reducing carbon emissions. These factors are propelling the adoption of PSA technology across diverse applications.

The Pressure Swing Adsorption Units Market is highly consolidated. Some of the market key players are Air Liquide, Air Products, Ally Hi-Tech, BOGE, CALORIC, Hanxing Energy, Haohua Chemical Science & Technology, Ivys, Linde, Lummus Technology, Parker Hannifin, Peak Scientific.

In March 2023, Parker Hannifin introduced a new range of portable, lightweight PSA units designed to support small-scale operations and enable use over longer distances.

In June 2022, Air Products and Cummins formed a partnership to collaborate on the development of hydrogen purification systems aimed at producing zero-emission hydrogen.
