Porous Alumina Ceramic Foam Filter (70mm*70mm*15mm)

Welcome to choose our Porous Alumina Ceramic Foam Filter, a high-performance filtration solution designed for industrial applications that require high purity, high temperature resistance, and long-term stability. Whether you are engaged in metal casting, ceramic production, environmental protection, or other industries, our filter can bring reliable filtration effects and help you improve product quality and production efficiency. Our porous alumina ceramic foam filter is made of high-purity alumina powder through advanced foaming and sintering technology. The strict production process ensures that the filter has a uniform and dense porous structure, which not only guarantees high filtration efficiency but also enhances its mechanical strength and high-temperature resistance. Unlike traditional filters, our product can work stably in high-temperature environments up to 1600°C, and it is resistant to acid, alkali, and other corrosive media, making it suitable for various harsh working conditions. The 3D interconnected porous structure is the core advantage of our filter. With optional pore sizes from 10 PPI to 100 PPI, you can choose the most suitable specification according to your specific filtration needs. The small and uniform pores can effectively trap impurities with a particle size of more than 5μm, such as oxides, slag, and other inclusions in molten metal, which helps to reduce defects in castings, improve the surface finish and mechanical properties of products. In addition, the porous structure also has good permeability, which can ensure smooth flow of the filtered medium without causing excessive pressure loss, thus not affecting the normal production process. Durability is another highlight of our product. The high-purity alumina material and advanced sintering process make the filter have excellent compressive strength and wear resistance. It can withstand the impact of molten metal or high-pressure fluid, and is not easy to break, crack, or deform during use. This means you can reduce the frequency of filter replacement, save maintenance time and costs, and improve production continuity. Our porous alumina ceramic foam filter has a wide range of applications. In the metal casting industry, it is widely used for filtering molten aluminum, copper, zinc, magnesium, and their alloys, which can effectively improve the purity of the molten metal and reduce casting defects such as pores, inclusions, and cracks. In the ceramic industry, it can filter ceramic glaze, remove impurities and bubbles, and improve the uniformity and gloss of the glaze surface. In the environmental protection field, it can be used for wastewater treatment, flue gas purification, and adsorption of harmful substances, contributing to green production. It can also be used as a catalyst carrier in the chemical industry, providing a large specific surface area for catalytic reactions. We pay attention to every detail of the product to ensure that you get a high-quality and reliable filter. The product is lightweight and easy to install, and we provide standard sizes (such as 100x100x50mm, 150x150x50mm, etc.) as well as customized services to meet the special needs of different customers. In addition, the filter is easy to clean and maintain: after use, you can clean it with high-pressure water or chemical cleaning agents, and it can be reused after drying, further reducing your use cost.
