Cerafil® Ceramic Filter Elements
Designed to withstand extreme temperatures and corrosive gases, Cerafil® provides reliable long-term particulate and gas removal, protecting downstream processes, reducing operational costs, and delivering clean, sustainable air solutions across diverse high-temperature industrial processes globally.
Advanced hot gas filtration for particulate and hazardous gas removal
Cerafil® ceramic filter elements are engineered for the highest performance in hot gas filtration. They remove particulate matter such as dust, smoke, and fumes, as well as hazardous gases including NOx, dioxins/furans, CO, and VOCs from elevated-temperature gas streams.
Developed using a precision injection-molding process, Cerafil® filters feature a dense outer surface that promotes cake filtration, prevents dust penetration, and ensures excellent filtration efficiency. Made from alumino-silicate fibers, they offer outstanding thermal resistance and durability even in the most demanding environments.
Since their launch in 1990, Cerafil® filters have proven their value in over 300 projects worldwide.
