The unplanned excavator downtime on a construction or mining site can cost thousands of dollars in lost productivity. And 70% of premature engine failures stem directly from inadequate air filtration in dusty working conditions. Our product SP-055031AT air filter is built for Komatsu excavators exclusively. It serves as a perfect drop-in replacement for OEM part numbers 4216035170, 421-60-35170, RD57962120, T1552005002 and SA12623. This filter is manufactured with heavy-duty filter paper and a rugged white housing. The brand-new cartridge filter can trap 99% of construction-site dust, sand, gravel particles and airborne debris before they enter your excavator’s engine. By maintaining clean intake airflow, it prevents catastrophic cylinder and piston wear and reduces excessive fuel consumption by up to 12%.With the production of our product,it can extend engine service life by thousands of operating hours. Precision-engineered to match original Komatsu specifications, it installs in minutes without any modifications, making it the ideal cost-effective solution for equipment fleet maintenance and emergency repair jobs.

Critical Installation & Maintenance Tips for Excavators
Thoroughly clean the entire air filter housing and intake tube before installing the new filter to remove any trapped dirt that could contaminate the engine.
In extremely dusty mining or demolition environments, reduce the replacement interval by 50% to maintain optimal engine protection.
Never attempt to clean and reuse this disposable paper filter with compressed air, as this will damage the delicate filter fibers and allow harmful particles to pass through.
Inspect the air filter daily when operating in heavy dust conditions, and replace it immediately if it becomes clogged or damaged.
Store spare filters in their original sealed packaging in a cool, dry location away from moisture and direct sunlight.
