For the castings and foundry industry, we offer four varieties of Ceramic Foam Filters: Alumina Foam Filters, Silicon Carbide Foam Filters, Zirconia Foam Filters and Silicagel Foam Filters. Compared with traditional filtering materials, our Ceramic Foam Filters offer high porosity (70%~95%), low loss of pressure, high specific surface area due to high porosity, high mechanical strength and chemical inertness which ensures no reaction with the molten metal being filtered in high temperature. The advantages include ease of operation, energy savings and low cost.
