Ceramic foam filters Arffil ceramic foam filters are characterized as high permeation rate, good strength and thermal shock resistance, stable quality and without loosing impurity in high temperature either in big size or small ppi products. Advantages compared with traditional filtering materials: Thermal and chemical stability in high temperatureücavoiding the chemical reaction with the filtered molten metal. High porosity and good mechanical strength in elevate temperature due to its pure ceramic composite. Full open cell without loosing ceramic particles or powders (snowing) during filtrating. Low head loss, easy operation, energy save. Make metal flow reposeful and avoid the sputtering and backset, this increases the surface quality of the cast, prevent the pore disfigurement and finally lower down the waster rate. Box quantity depends on the filters's dimensions
