OXYGEN GENERATORS
At On Site Gas Systems, we design and manufacture advanced oxygen generator systems using proven PSA (Pressure Swing Adsorption) technology. Our oxygen generators deliver high-purity oxygen on demand—eliminating the need for costly cylinder deliveries or bulk liquid oxygen. These systems separate oxygen from compressed air, delivering continuous oxygen supply with purities ranging from 90% to 99%.
Looking for a cost-effective, reliable way to produce your own oxygen? Our oxygen generators deliver high-purity oxygen on demand—eliminating the need for costly cylinder deliveries or bulk liquid oxygen. Whether you need a single oxygen generator or a fully engineered system, our solutions are built to match your exact flow, pressure, and purity requirements.
OXYGEN GENERATOR FAQS
What is an Oxygen Generator?
An oxygen generator (also known as an oxygen gas generator or oxygen generation system) produces oxygen by separating it from ambient air.
Using PSA technology, nitrogen is removed from compressed air, leaving behind a concentrated stream of oxygen. This process creates a continuous, on-site oxygen supply—without relying on third-party deliveries.
Key advantages of oxygen generators:
- Continuous oxygen production (24/7 supply)
- No delivery delays or shortages
- Lower long-term operating costs
- Improved safety vs. stored cylinders
- Scalable output as demand grows
What is Oxygen Gas?
Oxygen gas is a colorless, odorless, and highly reactive element that makes up approximately 21% of the Earth’s atmosphere. It is essential for life and plays a critical role in respiration, combustion, and a wide range of industrial processes.
In industrial settings, oxygen gas is used to enhance efficiency, increase combustion temperatures, and support chemical reactions. Common applications include metal cutting and welding, wastewater treatment, medical use, glass manufacturing, and aquaculture.
How Do Oxygen Generators Work?
Our oxygen generators use Pressure Swing Adsorption (PSA), a proven and efficient method for oxygen separation.
Here’s how it works:
- Compressed air enters the system
- Nitrogen is captured using a molecular sieve
- Oxygen passes through and is collected
- The system cycles continuously to provide a steady oxygen flow
This process ensures a reliable, uninterrupted oxygen supply with minimal maintenance.
What Are Oxygen Generators Used For?
Oxygen generators are used across a wide range of industries, including:
- Manufacturing & metal cutting
- Wastewater treatment
- Healthcare & hospitals
- Aquaculture & fish farming
- Glassblowing & metal fabrication
- Mining & mineral processing
- Food & beverage production
These systems provide consistent, high-purity oxygen for mission-critical applications worldwide.
What Type of Oxygen Generator Do I Need?
The right oxygen generator system depends on your specific requirements, including:
- Required oxygen purity level
- Flow rate and demand
- Operating environment
- Energy efficiency goals
- Mobility or scalability needs
Most industrial applications rely on PSA or VPSA oxygen generators due to their reliability, efficiency, and ability to deliver consistent oxygen purity.

When Air Compression is Simply Not Enough
Oxygen is an odorless and tasteless gas that is essential for life forms to function, including humans. It is the single most abundant element in the earth’s crust, making up close to half of all the elemental compositions. It can increase the temperature of a welder’s flame for localized melting of metal, making it useful for various cutting applications for steel and other metal alloys. It also plays a vital role for glassblowing artisans.
In silver and gold mining, oxygen is useful and more cost-effective at processing raw ore. It can double the yield of gold ore by the gravity method alone. Because oxygen produces a higher yield than traditional cyanide, it saves on resources. Oxygen generators are a safe and effective means of delivering pure gas directly on-site for ore processing.
Unlike stored oxygen tanks and other oxygen supply methods, a commercial oxygen generator is a safer option to supply critical gas on demand. Also called O2 generators, some of our oxygen gas generators can deliver oxygen with purity as high as 99 percent. This reliable purity percentage of our O2 generators have been utilized in hospitals around the world – including Portugal, Brazil, and China.
On Site Gas also manufactures portable oxygen generation systems (POGS). These oxygen generators are used in military hospitals and other field hospitals around the world. The POGS are used by many in Disaster Management around the world. Other applications in which oxygen generators provide benefits include public aquarium facilities, and cultivators of fish hatcheries as well. It is also useful in the treatment of wastewater at municipal facilities, as it helps feed the bacteria that is responsible for purifying the water to be utilized again.
