The Cartridge Filter Tube is a high-efficiency deep filtration medium designed for molten aluminum purification. Installed inside a cartridge filter box, it removes non-metallic inclusions, oxide films, and fine suspended particles from molten aluminum before casting.
Unlike surface filtration systems, cartridge filter tubes provide depth filtration, allowing molten metal to pass through a porous ceramic structure while capturing impurities throughout the filter body. This filtration mechanism helps achieve higher melt cleanliness and improved casting quality.
Manufactured from high-quality ceramic materials, cartridge filter tubes offer excellent thermal shock resistance, stable filtration performance, and long service life under demanding casting conditions.
