Donaldson Filters Guide

Donaldson at a Glance

Donaldson Company was founded in 1915 and is headquartered in Bloomington, Minnesota. It is one of the world's leading makers of filtration products for heavy-duty equipment, supplying air, oil, fuel, hydraulic, and exhaust filtration to truck makers, equipment manufacturers, and the aftermarket. Because Donaldson is both an original-equipment supplier and an aftermarket brand, Donaldson part numbers are widely used as a common reference, and buyers often search for a Donaldson number to find an equivalent filter from another maker.

Why Donaldson Part Numbers Are Used as a Reference

Many heavy-duty parts catalogs list a Donaldson number alongside the original manufacturer's number and the equivalents from other filter brands. A single Donaldson number therefore often connects an OEM number (for example from PACCAR, Perkins, MAN, or Iveco) with several equivalent filters. Knowing the Donaldson number can shorten the search for a replacement considerably, particularly for mixed fleets.

Donaldson Cross-Reference Quick Table

How to Use a Donaldson Cross-Reference Correctly

• Start from the engine and the existing filter, not from the number alone. The same Donaldson number can be listed for several applications, and not all of them are identical in detail.
• Compare dimensions, thread size, gasket, and bypass setting, not only the part number.
• For fuel filters, check the micron rating, since common-rail engines need the finest filtration.
• For air filters, check the seal type (radial seal or panel) and the housing.
• Keep a record of confirmed cross-references for your fleet so future orders are quicker.

Frequently Asked Questions

What is the Donaldson equivalent of Fleetguard LF14000NN? Catalogs commonly list Donaldson P550949 as the equivalent of Fleetguard LF14000NN (Cummins 4367100) for the Cummins X15 and ISX15.
