👉 A filling fluid, also known as antifoam or demulsifying agent, is a specialized liquid used in the automotive industry to prevent air bubbles from forming and rising to the surface during the filling process of engine oils, coolants, and other fluids. It works by reducing surface tension and creating a stable emulsion that traps air bubbles, ensuring a smooth and consistent flow into the fuel or coolant lines. This not only enhances the efficiency of the filling process but also protects the integrity of the fluid by preventing oxidation and contamination.
