DEF Filters

Baldwin Diesel Exhaust Fluid (DEF) filters remove contaminants to ensure proper function of your vehicle’s Selective Catalytic Reduction (SCR) system. If DEF is not filtered, urea crystals and other contaminants picked up during storage and handling can cause malfunction of the SCR system. A Baldwin DEF filter removes harmful particulate, preventing plugged dosing valves and enabling the SCR system to do the important job of reducing harmful Oxides of Nitrogen (NOx) emissions.
