The AF25962 from FLEETGUARD is a durable air filter integrated with Engine Guard technology, engineered for heavy-duty engines. It caters to construction, mining, and industrial machinery sectors—including specialized use in Liebherr excavators. It delivers robust contaminant protection for critical engine components while maintaining steady airflow. Meeting or exceeding OEM specifications, it effectively extends equipment service life. For operators facing rugged, high-dust working environments, this filter stands as a long-lasting choice to reduce maintenance downtime and minimize repair costs.

This filter utilizes premium multi-layered Engine Guard filtration media to achieve reliable purification results. It captures airborne dust, sand, abrasive particles, and fine debris as small as 0.3 microns, boasting a 99.8% filtration efficiency. Adhering to strict ISO 5011 standards, it targets contaminants that cause premature engine wear, cylinder damage, and performance degradation. Moreover, its reinforced media structure resists tearing and clogging—even in extreme dust conditions like mining sites or construction zones. 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 AF25962 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 2.2 lbs, the filter has a compact yet durable build: overall height of 14.9 in (378.46 mm), outer diameter of 5.95 in (151.13 mm), and inner diameter of 3.55 in (90.17 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 industrial operation, or in high-humidity conditions.

The AF25962 offers extensive compatibility with leading heavy-duty equipment brands, making it a versatile replacement option. It fits seamlessly with Liebherr excavator models and is cross-referenced with Mercedes part 0040949004 and Caterpillar part 1R0716. Beyond that, it serves as a reliable alternative to filters like Baldwin RS3670, Donaldson P532680, and Wix 46580. 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.
