Featuring durable polyurethane (PU) molded rubber end caps and protective outer steel mesh, this filter set delivers excellent seal integrity and superior anti-vibration performance under intense mining and dusty construction site operations. It is widely compatible with commercial heavy trucks, large wheel loaders, and engineering machinery operating in high-load environments.
Manufactured with high-efficiency moisture-treated wood pulp filter paper, the K3251 effectively traps sand, airborne dust, and abrasive particulate contaminants before entering the combustion chamber. Its uniform pleat layout maintains stable airflow, lowers intake resistance, prevents engine cylinder wear, and significantly extends operational maintenance cycles.
