Oxygen concentrator: apply zeolite molecular sieve as shift, adopt advanced physical theory(PSA) to separate oxygen and nitrogen in air, at the same time filter the bad subtance in air, 
so as to get pure oxygen for medical use.

Capacity 3L 5L 7L and 10L all can be available.
English version operation manuels will be supplied,
it is more convenient and easy for foreigners to operate.
