Product Overview
The PSA Nitrogen Generator System is an industrial on-site nitrogen production solution designed to generate high-purity nitrogen directly from compressed air using advanced Pressure Swing Adsorption (PSA) technology.
By utilizing high-performance Carbon Molecular Sieve (CMS), the system selectively separates nitrogen from oxygen and other trace gases, delivering a continuous and stable nitrogen supply for industrial applications.
Compared with traditional nitrogen supply methods (liquid nitrogen or gas cylinders), PSA nitrogen generation provides:
- Up to 90% reduction in nitrogen supply cost
- Continuous 24/7 on-site gas production
- No cylinder handling or logistics dependency
- Safer and more environmentally friendly operation
This system is widely used in industries requiring reliable nitrogen purity and stable gas supply performance.
Working Principle
The PSA nitrogen generator operates through two alternating adsorption towers.
Air Compression
Ambient air is compressed to a stable operating pressure using an industrial air compressor.
Air Purification System
The compressed air passes through multi-stage purification:
- Oil removal filter
- Dust filtration
- Moisture removal (dryer system)
Nitrogen Separation (Adsorption Phase)
Compressed air enters the adsorption tower filled with Carbon Molecular Sieve (CMS):
- Oxygen, CO₂, and moisture are adsorbed
- Nitrogen passes through as product gas
Regeneration Phase
The second tower is depressurized:
- Adsorbed gases are released
- CMS is regenerated for the next cycle
Continuous Operation
Two towers alternate automatically, ensuring:
Stable uninterrupted nitrogen production (24/7)

Engineering Selection Guide
To select the correct PSA nitrogen system, the following parameters must be defined:
Required Nitrogen Purity
- 95% → Inerting / blanketing
- 99.9% → General industrial use
- 99.999% → Electronics / high-end applications
Outlet Pressure
- Standard: 0.1–0.8 MPa
- High-pressure systems available (up to 8.0 MPa)
Nitrogen Flow Rate (Nm³/h)
Determines system size and compressor configuration.
Air Quality Requirement
Better air quality = higher efficiency and longer CMS lifespan.
