Nitrogen Generator Costs
The cost of a nitrogen generator depends primarily on the system type, required flow rate, and nitrogen purity level. At AGT, our nitrogen generation systems range from approximately $20,000 to $1,000,000+, depending on application requirements.
- Membrane nitrogen generators typically have the lowest upfront cost and are best suited for applications requiring less than 99% purity.
- PSA nitrogen generators require a higher initial investment but offer greater efficiency and lower operating costs for higher-purity applications.
- Installation, commissioning, compressed air systems, and maintenance can also affect total project costs.

Benefits of Onsite Nitrogen Generation
For any industrial operation that currently purchases nitrogen in delivered form, switching to onsite generation changes the operational and financial profile of that supply in several measurable ways including:
Up to 90% Lower Nitrogen Costs
Up to 90% Lower Nitrogen Costs
Nitrogen Supply Continuity
Scalable for Future Growth
Greater Operational Control
How to Choose the Right Nitrogen Generator
The decision between membrane and PSA technology is primarily determined by the purity requirement of the application and the volume of nitrogen required.
| Feature | Membrane | PSA (Modular or Twin Tower) |
|---|---|---|
| Purity Range | 95% to 99.5% | 95% to 99.999%+ |
| Best Purity Efficiency | Up to 98% | Above 98% |
| Operating Cost at Above 98% | Significantly higher than PSA | Most cost-efficient option |
| System Size and Weight | Compact, lightweight, fewer moving parts | Larger; pressure vessels and PLC controls required |
| Moisture Tolerance | More tolerant within limits | Sensitive to moisture; requires proper air drying |
| Mobile or Containerized Use | Well-suited | Less common |
| Scalability | Fixed capacity per module | Modular PSA: field-expandable |
For applications requiring nitrogen purity above 98%, PSA is the operationally correct and more cost-efficient choice. For applications in the 95% to 98% purity range where compactness, mobility, or simplicity of maintenance are priorities, membrane technology is the better fit. AGT's team can assess your purity requirement, flow rate, and operating environment to recommend the right configuration.

Frequently Asked Questions About Nitrogen Generators
What is a nitrogen generator?
A nitrogen generator is an industrial system that produces nitrogen gas onsite by separating it from compressed air. A nitrogen generator extracts nitrogen using either Pressure Swing Adsorption (PSA) or membrane technology, delivering a continuous supply of purified nitrogen gas at the purity and flow rate required by the application.
How does a nitrogen generator work?
A nitrogen generator works by separating nitrogen from oxygen and other gases in compressed air. PSA generators use carbon molecular sieve (CMS) to absorb oxygen in two alternating pressure vessels, producing nitrogen at purities up to 99.999%. Membrane generators pass compressed air through bundles of hollow-fiber polymeric membranes that selectively permeate oxygen, producing nitrogen at purities up to 99.5%. Both technologies require clean, dry compressed air as their input.
How much does a nitrogen generator cost?
Nitrogen generator prices vary based on technology type, flow capacity, and purity requirements. Small-flow systems start at approximately $20,000 and range up to $50,000. Mid-flow industrial systems cost between $50,000 and $200,000. Large industrial systems for high-demand operations range from $200,000 to over $1,000,000. Most nitrogen generators achieve return on investment within 9 to 24 months through savings on delivered nitrogen costs.
Where does Advanced Gas Technologies supply nitrogen generators?
We supply nitrogen generators across the United States, Canada, and Mexico, with installation and service capabilities offered globally through our extensive network of international industry partners.
What maintenance does a nitrogen generator require?
Routine nitrogen generator maintenance includes compressed air pre-filter replacement (typically every 8,000 operating hours), purity monitoring, pressure checks, and oxygen sensor calibration. PSA systems additionally require switching valve inspection and rebuild every 30,000-40,000 operating hours. The most critical maintenance requirement for all nitrogen generators is ensuring clean, dry compressed air. Contaminated air is the leading cause of premature system failure.
Should I choose a PSA or membrane nitrogen generator?
The choice depends on your purity, flow, and cost requirements. Membrane generators are typically more cost-effective for applications requiring purity below 98%, and they are compact, quiet, and very low maintenance. PSA generators are the better choice for applications requiring purity above 98% and up to 99.999%, and they are more energy-efficient at higher purity levels. Advanced Gas Technologies can help assess your application and recommend the right technology.
How long does a nitrogen generator last?
PSA nitrogen generators are typically designed for an equipment life cycle of 20 to 25 years. Membrane nitrogen generators can last 10 to 15 years before replacement is required. With proper maintenance, both types of generators can exceed these expected lifespans.
