Description
AF26433 & AF26434 FLEETGUARD Heavy-Duty Air Filter
The AF26433 and AF26434 from FLEETGUARD are rugged heavy-duty air filters, engineered specifically for industrial-grade engines. They serve construction, agriculture, and long-haul transportation sectors, delivering robust contaminant protection for critical engine components. Additionally, they maintain steady airflow while meeting or exceeding OEM specifications, effectively extending equipment service life. For operators navigating dusty, high-vibration environments, these filters stand as a reliable choice to cut maintenance downtime and minimize repair costs.
AF26433 Superior Heavy-Duty Filtration Performance
Both models feature premium multi-layered filtration media, achieving exceptional purification results. They capture airborne dust, sand, abrasive grit, and fine debris as small as 0.3 microns, boasting a 99.9% filtration efficiency. Moreover, they adhere to strict ISO 5011 standards, targeting contaminants that trigger premature engine wear, piston damage, and performance degradation. Their reinforced media structure resists tearing and clogging—even in high-dust conditions like construction sites or agricultural fields. With an outside-in flow design, they intercept pollutants on the media’s outer layer first. This ensures unobstructed airflow during extended service intervals, optimizing fuel combustion and sustaining reliable engine power.
AF26433 Robust Construction for Extreme Conditions
The AF26433 and AF26434 boast rugged constructions built to withstand heavy-duty operational demands. Their precision radial seal designs form tight, leak-proof fits with filter housings, eliminating bypass gaps that let unfiltered air enter engines. The AF26433 weighs 2.4 lbs, with an overall height of 15.2 in (386.08 mm), outer diameter of 6.1 in (154.94 mm), and inner diameter of 3.7 in (93.98 mm). Meanwhile, the AF26434 weighs 2.2 lbs, measuring 14.4 in (365.76 mm) in height, 5.9 in (149.86 mm) in outer diameter, and 3.5 in (88.9 mm) in inner diameter. Furthermore, their corrosion-resistant reinforced housings resist impact, vibration, and extreme temperatures from -25°F to 260°F. This sturdy design maintains structural integrity on rough job sites or during continuous long-haul operations.
