Donaldson Indicators

An indicator gives a visual or electrical signal that a filter has reached the end of its useful life, based on the pressure differential or restriction across it. It converts a condition nobody can see into something a fitter or an operator can act on, which is what makes filter changes condition-based rather than guesswork.

Types differ by whether the signal is visual, electrical or both, by the setting they trigger at, and by the port they fit. Search by Donaldson part number, or tell us the housing and setting.
