A pressure swing adsorption generator is a device that uses a process named “pressure swing adsorption” (PSA) to separate and purify gases. PSA is a technology that uses a bed of porous adsorbent material called zeolite to separate and purify gases. The generators selectively adsorbs one gas while allowing the others to pass through. The pressure swing adsorption generator alternates between two adsorbent vessels. One vessel is used to adsorb the target gas while the other is being depressurized to regenerate the adsorbent material. A pressure switch is controls the flow of gases and can alternate between the two vessels. Pressure swing adsorption generators are common to produce high-purity nitrogen, oxygen, and other gases for various industrial, medical, and scientific applications.
Why is PSA oxygen generation ideal for hospitals?

In a hospital setting, pressure swing adsorption (PSA) can generate high-purity oxygen for medical applications. By using a bed of adsorbent material to separate oxygen from the air, PSA technology can produce a continuous supply of oxygen with a high oxygen concentration (typically 95% or higher). This makes PSA an attractive option for hospitals, where a reliable supply of oxygen is essential for many medical procedures and treatments. PSA oxygen generators can be designed for portable or stationary use, and can be integrated into existing hospital gas delivery systems for ease of use. Additionally, PSA technology is low maintenance and energy efficient, making it a cost-effective solution for hospitals that need to produce oxygen on-site.
Can portable oxygen generators be used in a mobile hospital environment?
Yes, there are mobile hospital oxygen generators. These are compact and portable units that are designed to generate high-purity oxygen for medical use in a hospital setting. Mobile hospital oxygen generators use pressure swing adsorption (PSA) technology to separate oxygen from the air. Mobile oxygen generators produce a continuous supply of oxygen with a high concentration (typically 95% or higher). These units are typically equipped with wheels and a handle, making them easy to move from room to room or to different locations within the hospital. Some generators also come with built-in storage tanks for temporary storage of the generated oxygen. A regulator and flowmeter for adjusting the oxygen flow rate may be included as well. Mobile hospital oxygen generators are an ideal solution for hospitals that require a flexible and reliable source of oxygen, especially in emergency or critical care situations.
What are the advantages of a mobile oxygen generating system?
COST REDUCTION
- This system can reduce oxygen supply costs by 80% or more in most cases.
- Less than 1 kWh of energy is required to fill one ‘M’-size oxygen cylinder.
- Eliminate all delivery and handling charges from your current supplier.
DISASTER PREPAREDNESS
- By making oxygen and filling cylinders at your site, the uncertainty and logistics of delivered oxygen supplies are eliminated.
- With this system, care providers are assured that their oxygen supply chain will not be in jeopardy in a disaster.
- The system itself can also be transported for use at a disaster site. A truck can move it, fitting easily through a standard 36″ wide doorway.
