A clogged AF25414 filter restricts airflow, causing an improper fuel-to-air ratio. This leads to incomplete combustion and power loss. Inspect the filter every 250 hours if working in high-dust quarry or mining sites.
Dust particles can bypass the seal and enter the engine, acting as an abrasive. This causes rapid wear on the Crankshaft Bearings and Connecting Rod Bearings, eventually requiring a full Engine Overhaul.
Our filter features an OEM-standard tri-metal structure and high-performance media. It is trusted by repair shops and equipment fleets globally for its durability and precise fitment.
Our technical team helps operators and fleet managers maintain their assets efficiently:
Identify potential risks during maintenance to prevent costly downtime.
Recommend suitable replacement parts if needed based on your specific engine serial number.
Support both inspection advice and parts supply for one-stop maintenance solutions.
