Efficient nitrogen generator providing 99.5% nitrogen purity. Designed for reliable performance in industrial, laboratory, and food packaging applications.
The 99.5% 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), eliminating the need for traditional nitrogen cylinders or liquid nitrogen delivery.
The generator operates with a dual-tower adsorption system. During operation, compressed air enters one adsorption tower, where oxygen, moisture, and trace gases are selectively adsorbed by the CMS, while nitrogen passes through and is delivered to the outlet. At the same time, the second tower undergoes regeneration. A small portion of the produced nitrogen is used to release the adsorbed oxygen from the saturated CMS, and the exhaust gas is safely discharged into the atmosphere.
A PLC control system automatically switches the two towers every 45–60 seconds, ensuring uninterrupted nitrogen production and stable nitrogen purity at 99.5%. This process provides reliable performance, low energy consumption, fast start-up, and long service life, making it an ideal on-site nitrogen solution for industrial users.
To ensure stable nitrogen purity and efficient long-term operation, the nitrogen generator should be used under the following recommended conditions:
For the best performance, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including air filtration and drying, is recommended to protect the carbon molecular sieve, improve nitrogen generation efficiency, and extend equipment service life.

The 99.5% 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.
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.
