Air Filter Inner 3901465M2 - 3901465M1 Massey Ferguson

This inner safety air filter is engineered as a direct replacement for AGCO / Massey Ferguson part number 3901465M1, designed to protect the engine in the event of primary filter loading, damage, or unexpected bypass. As a secondary filtration element, it ensures clean intake air remains available even under severe dust loads, safeguarding critical engine components from abrasive contaminants. The filter features a 74,5 mm outer diameter, 62,5 mm inner diameter, and an overall length of 343 mm. These dimensions ensure a precise and secure fit inside the primary filter housing, maintaining proper airflow alignment and preventing contaminants from entering the intake system during primary filter servicing or failure. Classified as a Safety / Secondary filter and built in a round element configuration, this component is designed to work exclusively in conjunction with the corresponding primary air filter—not as a standalone filtration unit. It provides the final protective barrier to prevent unfiltered air from reaching the engine during filter changes or in cases of sudden primary element overload.
