Y-505W Professional Medical Oxygen Generator adopts lithium molecular sieve technology, with a formidable force of absorption. It can produce high solubility oxygen continuously and steadily. It has a special air duct design in the heat dissipation system, with a high-efficiency fan and a heat sink, which can significantly increase the usage of the machine without shutting it down. All these factors can avoid the reduction of oxygen concentration along with the decrease in the flow rate due to the overheating of the air. It also has an intelligent voice announcement system and a real-time digital display of oxygen flow which makes the process more user-friendly. The free setting of oxygen absorption time, automatic shutdown at a fixed time can reduce safety hazards. The design emphasizes the front operating area through proportional division, and the functional area is divided more scientifically. The larger handle makes it easier for the user to move the oxygen concentrator. The tilted angle of the whole machine provides a comfortable operating experience for users.
