AIR FILTER - ZFGAF924

The Fleetguard AF924 is an axial-seal secondary safety air filter that protects the engine intake whenever the primary cartridge is removed or compromised. The element stands 365.12 mm tall and uses an axial seal against the housing face for positive contaminant exclusion. It is positioned as the matched safety backup behind the AF923 and AF923M primary filters. The filter is designed for heavy-duty truck and bus engines requiring two-stage intake filtration with a dedicated safety element behind the main primary cartridge.
