Description of Operation

Air enters the Nidek Nuvo Family Oxygen Concentrator through an external cooling air intake filter. This filtered air enters the compressor via a suction resonator and fine filter, which quiets the suction sounds made by the compressor. Pressurized air then exits the compressor and passes through a heat exchanger, which reduces the temperature of the compressed air. Next, an electronic valve system directs the air into one of two sieve beds that contain a molecular sieve. The special characteristic property of a molecular sieve is that it physically attracts (adsorbs) nitrogen when air passes through this material, thus enabling the production of high-purity oxygen.

There are two sieve beds or adsorbent columns; while one produces high-purity oxygen, the other is purged of the nitrogen it adsorbed (collected) while it was producing oxygen. Each column produces oxygen for approximately 5.5 seconds and delivers it to the product storage volume in the end of the column. Oxygen exits the adsorbent column through a pressure regulator, flow control valve, flow meter, and final product filter. The flow control valve, which is part of the flow meter, controls the flow rate of oxygen delivered to the patient. The Nuvo Family unit delivers up to 95% oxygen concentration at rated flow. The remaining constituents of the product gas stream are nitrogen and argon, both of which are part of the air we breathe, are inert, and are completely safe. It’s a superb little oxygen machine
