OXYGEN ENRICHED AIR PRODUCING DEVICE AND OXYGEN ENRICHED AIR PRODUCING METHOD

摘要

The invention is characterized in: forming a magnetic field inside a flow channel tube the tube wall of which is formed from a material that is nonmagnetic and which when the pressure outside the flow channel tube is lower than the pressure inside the flow channel tube passes a portion of the air flowing inside the tube through the tube wall and discharges same to the outside thereof; supplying air to the flow channel tube so that at least a region of laminar flow is formed inside the flow channel tube; and reducing the pressure outside the flow channel tube to a prescribed pressure.
