3971070 Industrial Intake Air Filter Element | Size-Based OEM Replacement
The 3971070 air filter element is a size-based industrial intake air filter, commonly selected by dimensions and housing structure rather than a specific engine or equipment model.
It is widely used in industrial air intake systems, maintenance replacement scenarios, and OEM sourcing projects where consistent size, stable airflow, and reliable filtration performance are required.
This product is suitable for aftermarket replacement, bulk procurement, and factory-direct export supply.
This air filter is selected by outer diameter, inner diameter, and height, not by a specific engine model.
Please confirm dimensions and installation structure before ordering.
