The K2440 (PU2440) Air Filter Set is a premium heavy-duty dual-stage air intake filtration kit (outer primary filter + inner safety filter), engineered as a direct aftermarket replacement for Fleetguard AF25557 / AF25558, Donaldson P778637, and Weichai OEM Part Number 612600114993.
Featuring high-durability polyurethane (PU) molded end caps and outer protective steel mesh, this filter set ensures superior structural elasticity and airtight sealing against extreme vibration in mining and dusty construction sites. It is widely applied to 50-type wheel loaders and heavy machinery powered by Weichai WP10 and WP12 engines, including Lonking 855N, SDLG 955F, XCMG, Liugong wheel loaders, and Shacman engineering chassis.
Manufactured with high-efficiency moisture-resistant wood pulp filter paper, the K2440 effectively captures heavy dust, road sand, and fine particles before entering the engine combustion chamber. Its uniform pleat layout maintains stable airflow, lowers intake resistance, prevents cylinder wear, and extends engine operational life.
