Donaldson Restriction Indicators

A restriction indicator measures how much the air filter element is restricting intake airflow, and signals when it has reached the point where it should be changed. Restriction is the correct measure for an air filter: appearance is misleading, since a visibly dusty element is often still filtering well, while a partially blocked one can be starving the engine.

Indicators are specified by the restriction value they signal at and by their mounting. Search by Donaldson part number, or tell us the air cleaner and the setting required.
