Dispersion type oxygen generator series product USES the PSA (Pressure Swing Adsorption) technology separate the oxygen from nitrogen and other gas separation in the air.
The product uses oil-free compressor, medical molecular sieve, medical grade silicone tube high standard material. At normal temperature, as soon as power is connected, the oxygen which meets the medical standard can be separated from air constantly. Oxygen is generated by pure physical method. with steady oxygen flowing out, safe and reliable, low cost, adjustable flow. The key parts of the generator adopt anti-tiring and antiaging design.
This machine takes air as raw material, using molecular sieve pressure swing adsorption technology to produce oxygen concentration range of 90% to 90% (V/V) of oxygen (93% oxygen).
