Donaldson Filter Minders

A filter minder is a service indicator: it records the restriction an air filter has reached and holds that reading, so the element is changed on measured condition rather than on a guess or a calendar. It keeps a locked reading until it is reset, so it can be read at the next service rather than only while the engine is running.

Units are specified by their restriction setting and their mounting. Search by Donaldson part number, or tell us the air cleaner it is fitted to.
