Donaldson Blue® Fuel Filters

Engine and injector manufacturers tell you that you need the best available fuel filtration – and we agree! Today's engines operate in a wide range of environments that include vibration, fuel pump pulsation and surging fuel flows. It all adds up to big challenges for your fuel filters. 

On-engine fuel filters are your last chance to remove contaminant from your fuel system. It’s critical that your filters remove – and retain – as much contaminant as possible in all types of operating conditions. Donaldson Blue® filters with Synteq XP™ media technology provide premium protection for high pressure common rail (HPCR) fuel systems. They offer better contaminant removal and better contaminant retention under the challenging operating conditions your engines and equipment face every day. Donaldson Blue filters deliver the cleanest fuel – period.
