  Atmospheric pressure adsorption + vacuum desorption: the core technology of true industrial VPSA oxygen generation equipment   In the field of industrial oxygen production, PSA and VPSA pressure swing adsorption technologies are often confused, and many users find it difficult to distinguish which VPSA oxygen generator is truly suitable for large-scale industrial scenarios. In fact, industrial-grade VPSA oxygen generators are not simply an improvement on PSA technology, but rather an independent system with fundamentally different core technology routes, hardware configurations, and performance indicators, specifically designed for industrial oxygen needs that require high oxygen production, low energy consumption, and long-term stable operation.   I. Core Technology Route: Low-pressure adsorption + vacuum desorption is the essence of VPSA   The core feature of a true industrial VPSA oxygen generator ​ is that it adopts a pressure path of near-normal pressure adsor...
