Activated Carbon Fiber

Activated Carbon Fiber (ACF) is an innovative adsorption material developed from carbon fiber with a filament diameter of only 8–30 microns. Through specialized activation processes, millions of ultrafine micropores (average pore size around 20 Å) form on the fiber surface. These micropores significantly enhance adsorption performance for gases, vapors, pollutants, and organic compounds.

Compared with traditional granular activated carbon (GAC), activated carbon fiber offers faster adsorption, stronger capacity, quicker desorption, simpler regeneration, and higher efficiency, making it a preferred material in advanced purification systems.

Activated Carbon Fiber is a porous carbon material created by activating carbon-based fibers such as phenolic fiber, viscose fiber, or polyacrylonitrile fiber (PAN). The activation process develops a uniform microporous structure directly on the fiber surface, allowing pollutants to come into contact with active sites more efficiently.
