The role and principle of molecular sieve for oxygen generator

The medical oxygen generator is based on the pressure swing adsorption (PSA) technology, a new type of equipment that extracts oxygen from the air. It uses molecular sieve physical adsorption and desorption technology to fill the oxygen generator with molecular sieves, which can adsorb nitrogen in the air when pressurized , The remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The specific working process is that compressed air enters the adsorption tower through the switching valve after being purified by the air purification dryer. In the adsorption tower, nitrogen is adsorbed by the molecular sieve, and the oxygen is accumulated on the top of the adsorption tower and then enters the oxygen storage tank, and then filtered by the odor removal, dust removal filter and sterilization filter to obtain qualified medical oxygen. The main components are: air tank, air compressor, refrigeration dryer, oxygen generator, oxygen tank, etc.
The molecular sieve oxygen generator adopts the principle of pressure swing adsorption, uses air as raw material, does not require any additives, is connected to the power at room temperature, and adsorbs nitrogen and other gases through molecular sieve, which can separate more than 90% of medical oxygen from the air .


Molecular sieve oxygen generator is an advanced gas separation technology
The physical method (PSA method) directly extracts oxygen from the air, ready to use, fresh and natural, the maximum oxygen production pressure is 0.2 ~ 0.3MPa (ie 2 ~ 3 kg), there is no danger of high pressure and explosion.
Chemical oxygen generator
The chemical oxygen generator adopts a reasonable pharmaceutical formula and is used in specific occasions. It can indeed meet the urgent needs of some consumers. However, due to the simple equipment, troublesome operation, and high cost of use, a certain cost is required for each oxygen inhalation, and it cannot be used continuously and many other defects, so it is not suitable for home oxygen therapy.
