Pressure Switch Adsorption for Hospital Use

What is a pressure switch adsorption generator?

A pressure switch adsorption generator is a device that uses pressure swing adsorption (PSA) to separate and purify gases. PSA is a technology that uses a bed of porous adsorbent material to separate and purify gases by selectively adsorbing one gas while allowing the others to pass through. The pressure switch adsorption generator alternates between two adsorbent vessels, with one vessel being used to adsorb the target gas while the other is being depressurized to regenerate the adsorbent material. A pressure switch is used to control the flow of gases and alternate between the two vessels. Pressure switch adsorption generators are commonly used 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 be used to 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 in-house.

How 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, producing 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 mobile oxygen generators also come with built-in storage tanks for temporary storage of the generated oxygen, and may include a regulator and flowmeter for adjusting the oxygen flow rate. 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.


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 and all delivery and handling charges from your current supplier are eliminated.


By making oxygen and filling cylinders at your site the uncertainty and logistics of delivered oxyg en supplies are eliminated.

With this system in place care providers are also assured that in the event of a disaster their oxygen supply chain will not be in jeopardy.

The system itself can also be transported for use at a disaster site. It can be moved by truck and fits easily through a standard 36″ wide doorway.
