High Purity PSA Nitrogen Gas Generator (95~99.99%)
A PSA nitrogen generator (Pressure Swing Adsorption nitrogen generator) is advanced gas separation equipment that produces high-purity nitrogen (95~99.99%) from ambient air using the Pressure Swing Adsorption (PSA) principle. By utilizing the selective adsorption capacity of carbon molecular sieve (CMS) for oxygen and nitrogen, it achieves efficient gas separation without chemical reactions, ensuring stable and controllable nitrogen purity. The core advantage of onsite nitrogen generation eliminates logistical costs and safety risks associated with nitrogen cylinder transportation and storage, providing on-demand nitrogen supply for industrial processes. As a certified high-purity nitrogen generator, it integrates energy efficiency, automated operation, and robust design—backed by CE and ISO certifications to meet international quality and safety standards.
