The Diesel Particulate Filter (DPF) is a critical aftertreatment device designed to capture and remove particulate matter (PM), or soot, from diesel exhaust gases. Our DPFs feature advanced wall-flow ceramic substrates with precise porosity, ensuring high filtration efficiency (>95%) and low back pressure.
