The Donaldson Primary Air Filter is the perfect solution for heavy duty engine applications. Designed with an axial seal filter type and a round shape, this air filter fits perfectly into your Bobcat or Case equipment. The filter media material is made of high-quality cellulose, known for its superior filtration capabilities. The strong and pliable gasket of this air filter compresses against the air cleaner housing, creating a tight seal to prevent any contaminants from entering your engine. The high-efficiency cellulose media performs exceptionally well across a wide range of heavy duty engine applications, making it the perfect choice for those who demand the best. With more media pleats, this air filter has a higher dust holding capacity and longer filter life. The corrosion-resistant and coated steel liners support the media during operation, ensuring that the filter remains in top condition for longer. This also ensures uniform pleat spacing and prevents media from bunching, promoting a longer service life. FleetPride is your First Click in Heavy Duty®.
