Activated carbon granules are porous materials with strong adsorption capabilities. Their adsorption function is achieved through a combination of physical and chemical adsorption forces, and they appear black in color. The particle size of activated carbon directly affects its adsorption capacity. Generally, the smaller the particle size, the larger the filtration surface area. Activated carbon with different iodine values can be selected based on application requirements. Customized sizes are supported, with the conventional specification being L595 × W595 × H46 (mm). The outer frame material is available in two types: galvanized steel frame and aluminum alloy frame.
