The 99% PSA Nitrogen Generator is designed to provide a stable, continuous, and cost-effective nitrogen supply for a wide range of industrial applications. By using Pressure Swing Adsorption (PSA) technology, the system separates nitrogen from compressed air through high-performance carbon molecular sieve (CMS), delivering reliable on-site nitrogen production without the need for cylinders or liquid nitrogen.
The generator operates with a dual-tower adsorption system. During operation, compressed air enters one tower, where oxygen, moisture, and trace gases are selectively adsorbed by the CMS, while nitrogen passes through as the product gas. At the same time, the second tower enters the regeneration stage, releasing the adsorbed oxygen safely into the atmosphere.
When the first tower reaches saturation, the PLC control system automatically switches the adsorption process to the second tower while the first tower regenerates. This alternating cycle ensures uninterrupted nitrogen production, stable 99% purity, and consistent long-term performance for industrial use.
To ensure stable nitrogen purity and reliable system operation, the PSA nitrogen generator should be used under the following recommended conditions:
- Nitrogen purity: 99%
- Inlet temperature: ≤ 40℃
- Inlet pressure: 0.5 – 0.8 MPa
- Nitrogen dew point: ≤ -40℃
- Switching cycle: 45 – 60 s
- Ambient temperature: ≤ 40℃
- Voltage / frequency: 220V / 50Hz
- Noise level: ≤ 75 dB
For the best operating result, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including filtration and air drying, is recommended to protect the carbon molecular sieve, maintain nitrogen purity, and extend the service life of the equipment.

The 99% PSA Nitrogen Generator is well suited for Middle East industrial environments that require a stable, continuous, and cost-effective on-site nitrogen supply. In regional operating conditions that often include high ambient temperatures, dust exposure, and large-scale industrial operations, on-site nitrogen generation can reduce dependence on cylinders or liquid nitrogen while improving supply stability for everyday industrial use. It is especially suitable for sectors such as oil and gas, petrochemical processing, food packaging, metals, plastics, and general industrial manufacturing.

Application Note for the Middle East
For Middle East installations, this model should be supplied with clean, dry, and stable compressed air, especially because the recommended operating limits are inlet temperature ≤ 40°C and ambient temperature ≤ 40°C. In hotter regional conditions, proper air pretreatment, filtration, drying, and ventilation are important to protect the CMS, maintain nitrogen purity, and support long-term performance. This model is best positioned as a cost-effective on-site nitrogen solution for general industrial use, rather than as a substitute for ultra-high-purity specialty gas systems.
