To extend the lifespan of air filters in dusty and severe job-site conditions, the Komatsu pre-cleaner assembly dust cover component with part number 421-U12-3102 or 421U123102 is the preferred choice.
This air pre-cleaner assembly is compatible with D85EX-18, PC290-8, PC300-8, PC500-8, PC400-8, PC450-8, D85PX18E0, and PC300-8M0 heavy equipment models. By separating large dust, sand, and foreign particles from entering the air intake line before they reach the main filter, this structure directly contributes to maintaining stable engine performance.
Part Compatibility and Inspection
Prior to installation, matching the existing air filter and intake pipe diameters is crucial to ensure a complete seal. Depending on the dust density of your machine's operating environment, regular inspection of the dust collector bowl is recommended.
