Pre-Cleaner

Installed in a vertical orientation, this upstream separation stage serves as the initial dust-removal step in the air-intake train, reducing particulate loading before filtration. The housing length is 217.40 mm with a body diameter of 217.40 mm, and both inlet and outlet diameters measure 153.20 mm, enabling straightforward piping connections in compact engine compartments. The rated flow covers a low range of 14.20 cubic meters per minute and a high range of 1098.29 cubic feet per minute, providing substantial throughput to suit typical heavy-duty truck air systems without sacrificing filtration performance. Constructed to resist moisture and dust, the plastic body supports durable field service in harsh environments. By restricting debris sent downstream, it helps preserve the life of the main air filter and maintains consistent engine airflow. VMRS 041-001-001 places it within the standard maintenance framework, while cross references are not listed for this variant, suggesting direct compatibility within Donaldson’s pre-cleaner line. In the 71304 category, it is a practical solution for trucks and off-road equipment operating in dusty conditions, delivering reliable pre-cleaning without demanding complex installation.
