AF4878 - Air Filter, Primary

Engineered for peak performance in the world’s most punishing environments, the Fleetguard® AF4878 Magnum RS™ Radial Seal Primary Air Element is the ultimate defense for your heavy-duty machinery. When your equipment operates in high-dust or high-debris conditions, standard filtration simply isn’t enough. The Magnum RS™ line is specifically designed to go beyond basic requirements, offering a rugged construction that stands up to extreme vibration and temperature fluctuations. The standout feature of the AF4878 is its advanced radial seal technology. This design ensures a consistent, leak-proof bond between the filter and the housing, eliminating the risk of "dust bypass"—the leading cause of premature engine wear and catastrophic failure. By maintaining a high-capacity dirt-holding surface, this primary element significantly extends service intervals, reducing your total cost of ownership and minimizing downtime in the field. Whether you are managing a construction fleet, agricultural machinery, or industrial power systems, the Fleetguard® AF4878 provides the peace of mind that comes with superior engine protection. Its high-efficiency media captures even the smallest abrasive particles, ensuring that only clean, cool air reaches your engine’s combustion chamber. Invest in the Magnum RS™ advantage to ensure your equipment delivers optimum power and longevity, no matter how harsh the job site becomes. Choose Fleetguard for filtration that works as hard as you do.
