The AF25960 from FLEETGUARD is an efficient air filter integrated with Clean Air Core technology, engineered for heavy-duty engines. It caters to construction, agriculture, and long-haul transportation sectors, delivering reliable contaminant protection for critical engine components. It maintains steady airflow while meeting or exceeding OEM specifications, effectively extending equipment service life. For operators navigating dusty or high-stress working environments, this filter stands as a cost-effective choice to reduce maintenance downtime and minimize repair costs.

This filter utilizes premium multi-layered Clean Air Core filtration media to achieve exceptional purification efficiency. It captures airborne dust, sand, abrasive particles, and fine debris as small as 0.3 microns, boasting a 99.8% filtration rate. Adhering to strict ISO 5011 standards, it targets contaminants that cause premature engine wear and performance degradation. Moreover, its optimized media structure resists tearing and clogging—even in high-dust conditions like construction sites or agricultural fields. With an outside-in flow direction design, it intercepts pollutants on the media’s outer layer first. This ensures unobstructed airflow during extended service intervals, optimizing fuel combustion and sustaining consistent engine power output.

The AF25960 features a rugged construction tailored to heavy-duty operational demands. Its precision radial seal design forms a tight, leak-proof fit with the filter housing, eliminating bypass gaps that allow unfiltered air to enter the engine. Weighing 2.1 lbs, the filter has a compact yet durable build: overall height of 14.7 in (373.38 mm), outer diameter of 5.9 in (149.86 mm), and inner diameter of 3.5 in (88.9 mm). Additionally, its corrosion-resistant reinforced housing resists impact, vibration, and extreme temperatures from -25°F to 260°F. This sturdy design maintains structural integrity on rough job sites, during continuous long-haul operations, or in high-humidity conditions.

The AF25960 offers extensive compatibility with leading heavy-duty equipment brands, making it a versatile replacement option. It fits seamlessly with Caterpillar C7.1, C9.3, and 320 series models, as well as John Deere 6155M, 7155M, and 8155M series. Beyond that, it serves as a direct replacement for Caterpillar part 166-6665 and John Deere part RE504245, with cross-references to Baldwin RS3665, Donaldson P532675, and Wix 46570 filters. In terms of installation, its standardized size and straightforward design enable tool-free, quick replacement—no specialized training required. Furthermore, its lightweight yet sturdy build eases handling during maintenance, saving technicians time and reducing equipment downtime.
