Donaldson - On-Board Diesel Exhaust Fluid Filters (DEF)

The Diesel Exhaust Fluid (DEF) Filter offers a convenient, effective way to deliver clean DEF into your equipment.  If DEF is not filtered, urea crystals and other contaminants picked up during storage and handling can cause malfunction of the SCR system. The Donaldson Clean DEF Filter removes harmful particulate, preventing plugged dosing valves and enabling the SCR to do the important job of reducing harmful NOx emissions.
