The most widely used high-efficiency filtration system Equipment Introduction - The CFF Filtration Box (CFB) is widely used for molten aluminum filtration in the aluminum casting process to prevent the particulate impurities in molten aluminum from entering the casting blank and affecting the quality of aluminum products. -According to the quality requirements of castings, the volume of molten aluminum, the total volume of filtered aluminum, and the cleanliness of the aluminum itself, the correct selection of the type of filter box and the specifications of the foam filter plate help to achieve satisfactory filtration results. Main parameters of the CFB filtration box - Maximum temperature of molten aluminum: 750°C - Shell surface temperature: 70°C -Lining life: 12 months Common specifications of CFB filtration box Filtration Box Type Code Filtration Board Size inch Flow Range t/h Remarks Single-stage filtration box CFB1-12 12 2-5   A single filtration board is placed in the filtration box to filter out more than 85% of the inclusions with a particle size 8�¼m CFB1-15 15 4-10 CFB1-17 17 8-15 CFB1-20 20 12-20 CFB1-23 23 16-25 Horizontal two-stage filtration box CFB2-12/12 12/12 2-5 Two-stage filtration boards with different pore sizes from large to small are placed in the filtration box horizontally or vertically to filter out more than 95% of the inclusions with a particle size 8�¼m CFB2-15/15 15/15 4-10 CFB2-17/17 17/17 8-15 CFB2-20/20 20/20 12-20 CFB2-23/23 23/23 16-25 Vertical two-stage filtration box CFB2-15/12 5/12 2-5 CFB2-17/15 17/15 4-10 CFB2-20/17 20/17 8-15 CFB2-23/20 23/20 12-20 Two-channel filtration box CFB-12/12 12/12 2-52 Two channels in the filtration box for parallel arrangement of filtration boards of the same pore size. Used for continuous filtration of molten aluminum, one for use while the other as backup; used for filtration of large-flow or high-viscosity molten aluminum. Both channels meet the flow requirements together. CFB-15/15 15/15 4-102 CFB-17/17 17/17 8-152 CFB-20/20 20/20 12-202 CFB-23/23 23/23 16-252 Notes:Equipped with heating device as needed.
