A psa nitrogen generator (Pressure Swing Adsorption nitrogen generator) is a compact, mobile gas separation device engineered to produce 99.995% high-purity nitrogen at 20Nm³/h—designed explicitly for on-the-go and space-constrained applications. By leveraging the PSA principle, it extracts nitrogen from ambient air via selective adsorption of oxygen by carbon molecular sieve (CMS), eliminating the need for bulky cylinders or fixed installations. As a Portable Psa Nitrogen Gas Generator, it combines the core advantages of onsite nitrogen generation with mobility, delivering contamination-free nitrogen whenever and wherever required. Its status as a High-purity nitrogen generator ensures it meets the strict purity demands of precision applications, while the Energy-saving nitrogen generator design keeps operational costs low. Factory-direct supply guarantees superior quality control and competitive pricing, making it a trusted choice for industries needing flexible nitrogen solutions.

The psa nitrogen generation system of this portable unit operates through a streamlined adsorption-desorption cycle optimized for mobility and efficiency. Compressed air (from an external air compressor or built-in mini compressor, optional) undergoes two-stage filtration (oil and dust removal) to protect the CMS. The purified air is then pressurized and directed into the dual miniature adsorption towers filled with CMS: oxygen molecules are selectively adsorbed by the sieve, while nitrogen molecules (with weak adsorption affinity) pass through as 99.995% high-purity product gas. When one tower reaches saturation, the system automatically switches to the second tower for continuous supply, while the saturated tower undergoes depressurization and purge regeneration. This fully automated process ensures the psa nitrogen plant working efficiency remains above 94%, delivering stable 20Nm³/h flow and 99.995% purity—all in a compact, movable design that eliminates the constraints of fixed nitrogen systems.
The Factory Supply 20Nm³ Nitrogen 99.995% Portable Generator is tailored for scenarios requiring mobility and high purity, serving diverse industries:
- Field Engineering & Construction: Used for pipeline purging, welding protection, and inerting during on-site construction (e.g., oil and gas pipelines, municipal engineering). Its portability allows it to be transported to remote job sites, replacing cumbersome nitrogen cylinders.
- Laboratory & Research Institutions: Ideal for academic labs, pharmaceutical R&D, and material science research. 99.995% high-purity nitrogen supports experiments like sample preservation, gas chromatography, and inert atmosphere reactions—with the portable design fitting into limited lab space.
- Emergency Nitrogen Supply: Acts as a backup system for factories, hospitals, and data centers. In case of fixed nitrogen system failures, it provides immediate, on-demand nitrogen to prevent production downtime or equipment damage.
- Small-Batch Production: Suitable for small manufacturing workshops (e.g., precision parts, electronic components, and specialty chemicals). It delivers consistent nitrogen for product processing without the high cost of large-scale fixed generators.
- Marine & Offshore Operations: Compatible with Marine PSA Nitrogen Generator modifications, it serves as a portable solution for ships, offshore platforms, and marine engineering—used for pipeline purging, tank inerting, and corrosion protection.
Proper maintenance ensures the longevity and performance of your portable psa nitrogen generator:
- Filter Replacement: Replace pre-filter elements every 2-3 months (more frequently for dusty environments) to protect the CMS from contamination.
- CMS Maintenance: Monitor nitrogen purity monthly. Replace the CMS every 4-5 years (or if purity drops below 99.99%) to maintain adsorption efficiency.
- Mobility Parts Inspection: Check wheels, skids, and locks quarterly to ensure stable transportation and operation. Tighten loose components and replace worn wheels promptly.
- Control System Calibration: Calibrate the PLC, pressure sensors, and purity analyzer annually to ensure accurate monitoring and control.
- Storage & Protection: When not in use, store the generator in a dry, ventilated area. Cover it with a dustproof cloth to prevent component damage. For outdoor storage, use a weatherproof cover to protect against rain and extreme temperatures.
The Factory Supply 20Nm³ Nitrogen 99.995% Portable Generator redefines flexibility in nitrogen supply, combining the reliability of psa nitrogen generator technology with unmatched mobility.
As a High-purity nitrogen generator and PSA Portable Nitrogen Gas Generator, it delivers 99.995% pure nitrogen at 20Nm³/h, catering to field engineering, laboratories, emergency scenarios, and small-batch production.
