The molten aluminium filters are usually used in the standardized dimensions shown in inches with the porosity from 10 to 60 PPI (pores per linear inch). The ceramic foam filter size depends on its porosity and is selected with respect to the filtration capacity, time of casting and layout solution of the CFF filtration box. Selection of molten aluminium filter porosity is determined by the specific alloy, temperature of casting, metal pollution and requested output quality.<\/p>\n<p>Prior to casting itself, the filter has to be preheated adequately to secure its correct functioning. After completion of the campaign, the filter can be reused, if the CFF filtration box is equipped by permanent heating.
