Molecular sieve type oxygen machine works:

Process for the two towers. After feed air pressurized by the compressor, through the air pretreatment means to remove oil, dust and other solid impurities and water, and cooled to room temperature, treated by the compressed air through the intake valve into the Activated alumina adsorbent containing a molecular sieve, the air nitrogen, carbon dioxide is adsorbed effluent gas is the high purity oxygen, Tada when adsorbed to a certain saturation, the intake valve closed, the flush valve opens, the adsorption tower into the rinse stage, after the flush valve is closed, the valve opens desorption into the desorption regeneration phase, so that a complete cycle.
