The Donaldson P181099 Primary Round Air Filter delivers reliable filtration for heavy-duty engines operating in demanding environments. Its high-efficiency cellulose media captures 99.9% of airborne contaminants under ISO 5011 testing, helping prevent dust, dirt, and debris from reaching critical engine components.
A strong, compressible gasket creates a tight seal against the air-cleaner housing to help prevent unfiltered air from bypassing the media. Corrosion-resistant coated steel liners provide structural support and promote consistent airflow, while Donaldson’s Pleatloc™ design maintains uniform pleat spacing to support dependable performance and longer filter life.
Part of Donaldson’s EBB filter family, the P181099 measures approximately 13.84 inches in outside diameter, 9.49 inches in inside diameter, and 18.06 inches in length, with an overall length of 18.56 inches. It is used in select heavy-duty truck and engine applications. Always verify the part number, dimensions, and equipment compatibility before ordering.
