Working Principle

Air enters the compressor after filtered by the air inlet filter and is compressed into molecular sieve tower for separation of oxygen gas and nitrogen gas. Then, oxygen gas passes through the molecular sieve tower and enters the fine sieve tower smoothly, while nitrogen gas is discharged into the atmosphere through the separating valve after adsorbed by the molecular sieve. After the concentration of oxygen gas is further increased in the fine sieve tower, the flow rate is controlled by the flow control valve, and then oxygen gas is wet through the humidification water tank and finally flows through the oxygen delivery pipe for supplementary oxygen inhalation by users.

Product Description

This product adopts AC 220V (110V) voltage as power source, air as raw material, as well as pure copper oil-free compressor and imported high-quality molecular sieve with original packaging, so as to produce high-purity oxygen gas for supplementary oxygen for domestic use by a new Pressure Swing Adsorption (PSA) method under normal temperature. This product is designed as per the standard higher than that for house hold appliances and equipped with large and clear LED, intelligent chip automatic control circuit and automatic fault alarm function. It is easy to operate and provided with timing and overheat protection circuit. When the working temperature of the compressor is too high, it will stop working automatically to better protect the safety of the compressor and the whole machine. Moreover, this product is light and handy and easy to move, and it is suitable for not only household use but also vehicle-mounted use through the automotive power supply.
