Fleetguard AF4838 Air Filter

The Fleetguard AF4838 is a high-performance radial seal primary air filter, expertly engineered for medium and heavy-duty commercial vehicles matching Cummins, Dongfeng and Foton platforms. As an OEM-quality replacement part, it features precision structural design and tight dimensional control, ensuring seamless fit and reliable airtightness with the original intake system, effectively eliminating air leakage risks during long-distance transportation and complex road conditions.

Adopting high-quality composite fiber filtration media with optimized pore size, the filter delivers excellent particulate capture performance. It can efficiently trap road dust, sand and airborne contaminants, preventing abrasive particles from entering the engine and protecting key components like cylinders and pistons from premature wear, thus safeguarding stable engine operation for commercial vehicles.

Built with durable and lightweight materials, the filter balances structural strength and practicality. Its high-strength end caps and tear-resistant media enhance overall stability, and the streamlined airflow design reduces intake resistance while maintaining superior filtration efficiency, ensuring sufficient air supply for engine combustion and supporting fuel-efficient and powerful operation of commercial vehicles.

Advantages of AF4838 Air Filter

  • The AF4838 features superior and consistent filtration performance, with 3-5μm filtration precision and ≥99.99% filtration efficiency. It thoroughly captures fine particulates in road air, forming a solid protective barrier for the engine intake system, effectively reducing internal component wear and extending the service life of commercial vehicle engines.

  • It boasts perfect OEM compatibility and targeted applicability. Strictly designed to match the dimensional requirements of medium and heavy-duty commercial vehicles such as trucks and tractors, it enables quick and direct replacement without additional modification, greatly saving maintenance time and improving vehicle operational efficiency for fleets and operators.

  • The filter is engineered for long-lasting durability and road adaptability. Its rugged construction and high-quality materials resist vibration, temperature changes and dust erosion from complex road conditions, maintaining stable filtration performance during long-distance driving, avoiding premature failure and reducing unplanned vehicle downtime.

  • It offers excellent cost-effectiveness and fuel-saving potential. The optimized airflow design minimizes intake resistance, improving engine combustion efficiency and reducing fuel consumption to a certain extent. With a large dust holding capacity and extended service interval, it cuts down filter replacement and maintenance costs, maximizing economic benefits for commercial vehicle users.
