DEF/Urea Filtration

Of all the things that could shut down an engine, emissions violations may not be the first to come to mind. But if your equipment doesn’t meet EPA standards, it can’t make money for you. The key is to ensure your diesel exhaust fluid (DEF) stays free of debris that may plug dosing valves. Count on Fleetguard’s full range of DEF filters with proven, advanced technology to meet EPA standards so you can meet your productivity goals.
