YU300 & YU500 Oxygenerator abandon the cold and stiff industrialized models and use simple geometry and streamlined lines so that the machines can easily integrate into various home environments. Functionally, the air intake perfectly combines with the side hand-buckle, and the air vent is hidden in one side of the machine on the bottom; the built-in tank hides inside the machine, which design not only keeps the product integrity, but also enhances product details. These products use Gas Assisted Injection Molding, not only reducing noise, but also solving the problem of difficult processing and easy shrinking due to the thick wall.
