P549644

AIR FILTER, PRIMARY RADIALSEAL

The Donaldson P549644 is a primary radial seal air filter built for heavy-duty diesel engines. It uses high-efficiency cellulose media and a RadialSeal™ gasket that prevents leaks even under strong vibration. Corrosion-resistant coated steel liners and Pleatloc™ technology keep pleats evenly spaced, helping maximize airflow and extend service life. Replace this filter as part of your regular maintenance schedule, typically when the restriction indicator shows high restriction or at the interval recommended by the engine maker.
