AI Technical Summary
Technical Problem
Existing oxygen concentrators face challenges with high operating pressure, high energy consumption, and large equipment size, particularly in achieving a compact, low-pressure, continuous-flow, and high-production design.
Method used
An oxygen concentrator equipped with filter assemblies driven by rotating cells with controlled speed, combined with small filter tubes, providing continuous flow and using molecular sieves for nitrogen retention, operates at low pressure and high efficiency.
Benefits of technology
The solution achieves a compact, low-pressure, continuous-flow oxygen concentrator capable of producing 90 liters/minute with reduced energy consumption and smaller equipment size.
