A psa nitrogen generator (Pressure Swing Adsorption nitrogen generator) is an advanced industrial device that adopts PSA technology to separate nitrogen from atmospheric air via the selective adsorption property of carbon molecular sieves (CMS). As a professional manufacturer, we specialize in producing automatic High Purity 99.999% N2 Generator models certified with CE and ISO, which are engineered to meet the stringent purity requirements of high-end industrial applications. As a high-purity nitrogen generator, it delivers nitrogen with impurity content below 100 ppm, ensuring stable and reliable inert gas supply for precision manufacturing, electronics, and pharmaceutical industries. Its core advantages include fully automatic operation, minimal human intervention, and compliance with international quality standards, making it a cost-effective alternative to cryogenic nitrogen production methods while guaranteeing ultra-high purity output.


99.999% purity nitrogen, also known as “5N nitrogen”, is a critical auxiliary material for industries where even trace impurities can lead to product defects or process failures. Our psa nitrogen generator is specifically designed to produce this ultra-high-purity nitrogen, making it suitable for semiconductor wafer fabrication, where nitrogen is used for purging vacuum chambers and preventing oxide formation on sensitive chip surfaces. In the pharmaceutical industry, it serves as a substitute for Pharmaceutical Grade PSA Nitrogen Generator in sterile production processes, such as API synthesis and lyophilization, ensuring compliance with GMP standards. For aerospace component manufacturing, 99.999% purity nitrogen is used for inerting heat treatment furnaces, avoiding contamination of high-strength alloys. Unlike lower-purity nitrogen generators, our Pressure Swing Adsorption High Purity Nitrogen Generator integrates a two-stage purification system (including catalytic deoxidation and high-efficiency filtration) to remove trace oxygen and moisture, ensuring that the output nitrogen meets the strictest industrial purity requirements.
The modular nitrogen generator design of our 99.999% purity model offers unparalleled flexibility for enterprises with different space and production requirements. Small-scale users such as research laboratories can choose a compact standalone module that occupies less than 3 square meters of floor space, while large industrial facilities can opt for a multi-module system to meet high-flow demand. For enterprises with limited indoor space or those requiring quick deployment, the container type PSA nitrogen generator is an ideal choice—it is fully assembled in a standard shipping container, equipped with all necessary components including compressors, purification modules, and control systems. The containerized unit can be placed outdoors, connected to the power supply and production line via pipelines, and put into operation within 48 hours without complex civil engineering. For mobile applications such as on-site precision processing projects, the Portable Psa Nitrogen Gas Generator variant provides a compact and mobile solution, delivering 99.999% purity nitrogen anytime and anywhere.
CE and ISO certifications are critical for industrial equipment to enter global markets, and our psa nitrogen generator is fully compliant with these international standards. CE certification ensures that the equipment meets EU safety, health, and environmental protection requirements, while ISO 9001 certification reflects our strict quality management system throughout the production process. ISO 14001 certification further demonstrates the equipment’s environmental friendliness, with low energy consumption and zero harmful emissions. For enterprises exporting products to Europe, North America, and other regions, using our certified nitrogen generator helps their production processes meet international quality standards, avoiding trade barriers caused by non-compliant equipment. Additionally, our equipment is tested and certified by third-party institutions to ensure that its 99.999% purity output is consistent and reliable, providing users with peace of mind.
