FLEETGUARD

The Fleetguard AF25139M is a Magnum-series premium axial-seal primary air filter built for heavy-duty Class 8 on-highway tractors. The pleated cellulose pack delivers ISO 5011 99.9% full-life efficiency, capturing fine roadway dust before it can reach the turbocharger and combustion chamber. Sized at 387 mm long and 326 mm largest outside diameter, it is the Magnum RS replacement for AF4908 and is fitted as the primary air element on Class 8 long-haul prime movers. It is paired with safety filter AF25345.
