Compact PSA Oxygen Generating System,Equipped with Zeolite molecular sieve as the adsorbent, PSA Oxygen Generator can separate oxygen from the surrounding air by adsorption and release of nitrogen. Oxygen concentrations can be 93%(±3%).
Zeolite is with three-dimensional structure which forms uniformly sized pores. As the pores preferentially absorb small molecules and exclude large molecules, Zeolite acts as molecular sieves. Zeolite molecular sieve will absorb nitrogen and separate high purity oxygen under high pressure; it will release nitrogen at low pressure. Two adsorption towers process nitrogen adsorption and release.
Once Zeolite molecular sieve in tower A absorbs enough nitrogen, tower A will stop the separation process and begin to release nitrogen into the nitrogen storage tank. Tower B will begin to separate the oxygen. Two towers separate oxygen alternately.
