AF26656 FLEETGUARD Reliable Air Filter – Combustion Core
The AF26656 from FLEETGUARD is a reliable air filter integrated with Combustion Core technology, engineered for heavy-duty engines. It serves construction, agriculture, and long-haul transportation sectors, delivering steadfast contaminant protection for critical engine combustion systems. Additionally, it maintains consistent airflow while meeting or exceeding OEM specifications, effectively extending equipment service life. For operators navigating high-dust, high-vibration work environments, this filter stands as a trustworthy choice to cut maintenance downtime and minimize repair costs.
Dependable Combustion Core Filtration Performance
This filter features premium multi-layered Combustion Core filtration media, achieving exceptional purification results. It captures airborne dust, sand, abrasive particles, and fine debris as small as 0.3 microns, boasting a 99.8% filtration efficiency. Moreover, it adheres to strict ISO 5011 standards, targeting contaminants that trigger premature engine wear, combustion inefficiencies, and performance degradation. Its reinforced media structure resists tearing and clogging—even in extreme dust conditions like construction sites or agricultural fields. With an outside-in flow design, it intercepts pollutants on the media’s outer layer first. This ensures unobstructed airflow during extended service intervals, optimizing fuel combustion and sustaining reliable engine power output.
AF26656 Robust Construction for Harsh Environments
The AF26656 boasts 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 let unfiltered air 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). Furthermore, 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.
