FLEETGUARD

The Fleetguard AF55312 is a Direct Flow secondary safety air filter built on cellulose media to protect the engine intake when the primary is removed or compromised. The element has an overall width of 179.60 mm and uses non-flame-retardant cellulose media for standard service. It is positioned as the safety backup behind matching Direct Flow primaries in the same housing platform. The filter is designed for heavy-duty truck and bus engines that rely on the Direct Flow system for compact, high-efficiency intake filtration.
