Oxygen Generators
At Advanced Gas Technologies (AGT), we supply, install, and maintain industrial onsite oxygen generation systems for facilities across the United States, Canada, Mexico, and international markets. Since 1994, we have helped industrial operations in sectors such as manufacturing, mining, wastewater treatment, aquaculture, and healthcare eliminate dependence on delivered cylinder and bulk liquid oxygen. By generating oxygen onsite, our customers can reduce their ongoing oxygen costs by up to 70%.
We provide two proven oxygen generation technologies designed to meet different production needs. Our Pressure Swing Adsorption (PSA) systems serve small to mid-scale operations requiring dependable onsite oxygen supply, while our Vacuum Pressure Swing Adsorption (VPSA) systems are designed for high-volume, continuous-duty applications. Each oxygen generation system is delivered as a turnkey solution supported by our 24/7 service network.

- Best Suited for: Moderate, continuous, or variable oxygen demand in space-constrained facilities
VPSA Oxygen Generators
Our VPSA oxygen generators can be configured for scalable capacity to support increasing production demands. They operate at lower pressure using a blower and vacuum-assisted process, reducing energy consumption per unit of oxygen produced while maintaining consistent output.
Each system operates automatically with fast start-up and stable performance under continuous duty. They include remote monitoring and control capability, adjustable pressure and oxygen purity settings, and are delivered as complete turnkey systems covering design, installation, and commissioning.
Key Specifications:
- Purity Range: Up to 93%
- Flow Capacity: 1 metric ton/day to 100 metric tons/day
- Discharge Pressure: 100 psig (7 barg) with a booster compressor
- Lifespan: 20+ years with routine maintenance
- Best Suited for: High-volume, continuous operations such as large aquaculture, mining, and water treatment facilities
Oxygen Generator Costs
The cost of an industrial oxygen generator ranges widely, from $5,000 for small commercial units up to $1,000,000+ for massive plant systems. The exact price depends entirely on your required capacity, purity, and production method.

Benefits of Onsite Oxygen Generation
Industrial operations that rely on cylinder or bulk liquid oxygen delivery are absorbing costs and operational risks that onsite generation eliminates entirely. Once an AGT system is installed and commissioned, your facility can benefit from:
Up to 70% Lower Oxygen Costs
Improved Facility Safety
Uninterrupted Oxygen Supply
Full ROI in 6 to 36 Months
Greater Operational Control
How to Choose the Right Oxygen Generator
The right oxygen generation technology depends on your application's volume requirements, pressure specifications, and energy consumption profile.
| Feature | PSA | VPSA |
|---|---|---|
| Purity Range | 93% to 95% | Up to 95% |
| Best Purity Efficiency | 90% to 95% | 90% to 95% |
| Capital Cost | Lower upfront | Higher upfront |
| Energy Use | Higher per unit at large volumes | Significantly lower per unit at volume |
| System Size and Weight | Compact and lightweight | Larger footprint and heavier |
| Mobile or Containerized Use | Well-suited depending on size | Less practical |
| Scalability | Moderate | High |
PSA is the practical choice when oxygen demand is moderate (up to 4,000 SCFH), when higher output pressure is required without a booster, or when operational simplicity is a priority. VPSA delivers lower per-unit operating costs and superior scalability for high-volume, continuous operations where energy efficiency over time is the primary consideration.

Frequently Asked Questions About Oxygen Generators
What are oxygen generators?
Oxygen generators are industrial systems that produce oxygen on demand from ambient air, eliminating the need for delivered cylinder or bulk liquid oxygen supply. They work by separating oxygen from the other gases in atmospheric air using a molecular sieve material and a pressure-based adsorption process. The result is a continuous, on-site source of industrial-grade oxygen at the purity and flow rate the process requires.
How does an oxygen generator work?
Both PSA and VPSA oxygen generators use a material called zeolite, a molecular sieve that selectively adsorbs nitrogen from compressed air, leaving a concentrated stream of oxygen to flow through for process use. In a PSA system, compressed air is passed through zeolite-filled pressure vessels at high pressure. Nitrogen is captured by the zeolite, and oxygen exits as the product gas. The vessels cycle between adsorption and regeneration phases to produce a continuous output.
VPSA operates on the same principle but at lower pressure, using a vacuum pump during the desorption phase to regenerate the zeolite. This lower-pressure approach consumes less energy per unit of oxygen produced, making it the preferred technology for large-scale, continuous-duty applications. Both system types are fully automatic and require no operator intervention during normal operation.
How much does an oxygen generator cost?
The cost of an onsite oxygen generator depends on the system type. PSA systems suited to small and mid-scale operations represent a lower upfront investment, while large VPSA installations for high-volume continuous operations require a higher capital outlay.
At AGT, oxygen generation systems range from approximately $5,000 to $1,000,000+. However, installation, commissioning, compressed air systems, and booster compressors can also affect total project cost. For an accurate cost estimate based on your specific application, contact AGT.
What maintenance does an oxygen generator require?
Onsite oxygen generation systems are designed for low-maintenance, long-term operation. Routine maintenance typically includes periodic filter replacement, valve inspection, verification of controller settings and alarm functions, and scheduled checks of the compressed air feed system. AGT provides maintenance support for all systems it installs, including preventative maintenance programs and 24/7 emergency service.
Where does Advanced Gas Technologies supply oxygen generators?
AGT supplies, installs, and maintains oxygen generation systems throughout the United States, Canada, and Mexico, and deploys internationally through a network of qualified industry partners.
Should I choose a PSA or VPSA oxygen generator?
The right technology depends on your application's oxygen flow volume requirements, required purity, operating pressure, and energy consumption priorities. PSA is the practical choice for operations requiring up to 4,000 SCFH, higher output pressure, or where a compact footprint and operational simplicity are priorities. VPSA is better suited to large-scale, continuous-duty operations where high-volume output and lower energy consumption per unit of oxygen produced are the primary considerations. If your application sits at the boundary between the two technologies, AGT's engineering team can evaluate your specific requirements and recommend the most appropriate system configuration.
How long does an oxygen generator last?
AGT’s onsite oxygen generation systems can operate reliably for 20 years or more with routine maintenance.
