Donaldson P607557 Safety Air Filter Element

The Donaldson P607557 is a safety (secondary) air filter element designed to function as a backup filter within two-stage PowerCore PSD12 air cleaner assemblies. It protects the engine during primary filter servicing or in the event of primary filter damage. The element features an obround (oval) honeycomb filter media configuration with metal end caps and an integrated pull handle for secure installation and removal. Constructed to meet ISO 5011 test standards, the filter utilizes high-efficiency cellulose/synthetic blend media to capture fine particulates that bypass the primary element. It is a direct replacement for OEM references including Case 87356547, Bell 226780, AGCO 568311D1, and JCB 334R1769. The filter serves as the inner element paired with primary filters such as Donaldson P608667 or P608677. Cross-reference interchangeability covers Fleetguard AF4201, Baldwin PA5792, Wix 49557, Mann CF37001, and Napa 9557. Applications span heavy-duty on-highway trucks (Freightliner MT45/MT55, Ford F650/F750), construction machinery (Case IH Patriot sprayers, New Holland loaders, JCB excavators), and industrial engines (Cummins QSX15, ISB 6.7).
