AF25352 AF25558 Air Filter | Heavy Duty Truck & Construction Machinery Filter

AF25352 & AF25558 Air Filter | Heavy Duty Truck & Construction Machinery Filter

The AF25352 outer main air filter paired with the AF25558 inner safety core forms a complete dual-stage air filter set. It is a high-performance OEM replacement filter designed for heavy-duty trucks and construction machinery. This filter combo effectively cleans engine intake air by blocking sand, dust and fine airborne particles, protecting internal engine components and extending overall engine service life.

We are a professional manufacturer of heavy-duty filtration parts. All our AF25352 and AF25558 air filters adopt premium filter media and precision manufacturing standards. They deliver stable performance, excellent durability and strong adaptability to harsh working environments, making them the top choice for bulk buyers, including overseas auto parts wholesalers, construction fleets and equipment maintenance workshops.

• Model: AF25352
• Structure: Outer primary air filtration layer
• Filter Material: High-density imported fiberglass filter paper with reinforced metal inner mesh
• Function: Traps large contaminants such as sand, coarse dust and debris to ensure consistent and clean primary air intake

• Model: AF25558
• Structure: Inner secondary safety filter core
• Filter Material: Thickened composite high-efficiency filter paper
• Function: Provides backup secondary filtration. It blocks fine dust and prevents engine contamination if the outer AF25352 filter is damaged or compromised

The combined AF25352 + AF25558 filter set is mandatory for harsh operating conditions, including mining sites, construction zones and long-distance highway transportation. Dual-stage filtration delivers maximum engine protection. For clean and flat road environments, the single AF25352 main filter can be used independently.

• High Filtration Accuracy: Uniform micro-pore structure captures over 99.5% of fine dust particles, fully protecting engine cylinders, pistons and key moving parts from abrasive wear.
