<p style="text-align: justify; ">Learning from series physical theory, The core part -- spiral tube is a three-dimensional mesh structure welded by red copper wires. These metal meshes can make the fluid forming a relatively static area to block the flow. lt makes the speed and pressure of the water flow changing , then releases bubbles. A large number of bubbles are gathered or the metal mesh due to molecular force, and the impurities are separated from the fluid by the difference in specific gravity. The separated gas and impurities are collected separately in the top vent cabin and bottom dirt storage bin . The collected gas is automatically exhausted in real-time through the top vent function , and the impurities are discharged through the bottom drain valve.<br></p>
