FIELD: medical and biological industries; may be used in cleaning of oxygen by method of adsorption into two fractions. SUBSTANCE: adsorption plant has two installed parallel columns with adsorbent and connected by means of branch pipes with gas-supplying pipeline; throttling device and control unit which consists of valves unit and valve control unit including unit of time of simultaneous filling of one adsorber and emptying of the other one; time delay unit; pressure comparison time unit and switching unit. Valves control unit is provided with pneumatic signal amplification unit connected with switching unit and pressure comparison time unit. Unit of time simultaneous filling of one adsorber and emptying the other consists of pressure setter, time setter and gas-operated flip-flop. Time setter is connected with time delay unit and switching unit. Gas-operated flip-flop is connected with pressure comparison time unit. EFFECT: higher reliability. 1 cl, 5 dwg
