Aluminium alloys need to meet ever more stringent quality requirements, particularly for beverage cans, foils, fine wires,lithographic sheets and bright trims. In fact, inclusions lead to problems when metal is produced to ever decreasing thicknesses approaching those of the inclusion size or when surface quality is paramount. The FRALCO Deep Bed Filter consists of an insulated box containing layers of carefully sized alumina balls through which molten aluminium flows from top to bottom. The filtering area, or bed, is sized as a function of metal flow rates Advantages 5μm Inclusion removal efficiency higher than 95%, LiMCA and PoDFA analyses show best quality requirements consistently achieved with DBF; Different ball sizes and variable layers allow custom quality requirements. Excellent constancy and repeatability of results; Productivity Environment.Preheat station permits quick change of filter box to avoid downtime. Large volumes can be treated before cleaning of filter boxes is required. Flow rates of up to 90t/h can be processed.   Module capacity Static metal（KG）  Dimension （L*W*H） MDBF-5 5t/h 470 1823 x 1770 x 1950   MDBF-10 10t/h 600 2030 x 1770 x 1950 MDBF-15 15t/h 800 2330 x 1770 x 1950 MDBF-20 20t/h 1150  2440 x 2140 x 1950 MDBF-25 25/h 1300 2500 x 2100 x 1950 MDBF-30 30t/h 1400 2540 x 2240 x 2000 MDBF-35 35t/h 1680  2770 x 2400 x 2000 MDBF-40 40t/h 1850 2870 x3000x 2000 MDBF-55 55t/h 3030 2980 x 3200 x 2320 MDBF-75 75t/h 3600 3000 x 3600 x 2320 MDBF-90 90t/h 4950  3000 x4100 x 2320
