PURPOSE: An apparatus for purifying and supplying oxygen in air is provided which supplies stabilized oxygen by purifying the air considering the number of towers according to flux and purity of the air by receiving air in the low pressure state, thereby producing oxygen having certain purity and flux. CONSTITUTION: In an apparatus(1) for supplying separated oxygen by separating oxygen contained in air from the air, the apparatus comprises a compressor(6) for coercively sucking in an external air through main supply pipe(5); a rotary distribution valve(10) for sequentially supplying the distributed air having certain pressure and flux to separating and purifying units installed in series and in a row through branch pipes by distributing the air sucked into the main supply pipe; and separating and purifying units(30-1,30-2,30-3,30-4) for discharging the oxygen and nitrogen through main discharge pipe(8) by separating the air into oxygen (O2) and nitrogen (N) after receiving the distributed air from the rotary distribution valve.
