The AF25308 FLEETGUARD is a high-efficiency air filter featuring the Clean Core technology, specifically engineered for heavy-duty engines in agriculture, construction, and commercial transportation. It excels at shielding critical engine components from harmful contaminants while maintaining unobstructed airflow, meeting or exceeding OEM specifications to extend equipment service life. It’s a reliable choice for operators aiming to reduce maintenance downtime and minimize repair costs.

This filter leverages premium multi-layered Clean Core filtration media to deliver top-tier filtration results. The media effectively captures airborne dust, sand, and abrasive particles as small as 0.3 microns, with a 99.9% filtration efficiency. It adheres to strict ISO 5011 standards, targeting fine contaminants that cause premature engine wear. What’s more, its outside-in flow direction design intercepts pollutants on the media’s outer layer first, preventing clogging and sustaining consistent airflow during long-term use. This balance between filtration precision and airflow ensures optimal fuel combustion and reliable engine power output.

The AF25308 boasts a robust construction built to withstand the rigors of heavy-duty operations. Its precision radial seal design forms a tight fit with the filter housing, eliminating bypass gaps that allow unfiltered air to enter the engine. Weighing 1.68 lbs, the filter features a compact yet durable build: overall height of 12.31 in (312.74 mm), outer diameter of 5.08 in (129.03 mm), and inner diameter of 3.2 in (81.28 mm). This rugged design resists vibration and impact from equipment operating on rough terrain, maintaining structural integrity even during continuous use on construction sites or agricultural fields.

The AF25308 offers extensive compatibility with leading heavy-duty equipment brands, making it a versatile replacement option. It fits seamlessly with John Deere models including 5200, 5300, and 6320, as well as McCormick and Case International’s C50, CX60 series. It also serves as a direct replacement for Toyota part 17741U210071 and John Deere part RE68048, with cross-references to Baldwin RS3549, Donaldson P532410, and Wix 46489 filters. In terms of installation, its standardized size and straightforward design enable tool-free, quick replacement—no specialized training required. This user-friendly feature saves technicians time during maintenance and reduces equipment downtime.
