Informative Filtration Knowledge
from Donaldson Engineers
OVERVIEW

There are numerous items to consider when deciding on
your liquid filtration supplier during the design of a new
engine, vehicle or stand-alone piece of diesel-powered
equipment. Our experience in the design and production of
liquid filters began in 1975 (hydraulic filtration). In the early
1980s, we expanded into lube filtration and then on to fuel
and coolant filtration. With over 25 years of experience,
you will be working with a financially strong, diversified
company with a global infrastructure that offers unique and
quality filtration products. If a custom-designed solution
is not what you require, we have a wide variety of stock
solutions that offer you application flexibility with filtration
performance choices that will improve, enhance and protect your engine components.

Fuel Filtration

OEMs need more efficient fuel filtration systems
with longer life in a smaller overall package in
support of high pressure fuel injection systems.
Learn about the features of a system and
associated benefits that allow you to weigh the
merits of one system’s features vs. another. For
new systems, our heads and filter pages provides
the off-the-shelf options where you can select the
proper filter to meet your engine specifications.

In our fuel blue pages, learn more about biodiesel and alternative fuels and their
affect on fuel filtration. The blue page section will help provide a greater understanding of fuel and fuel systems.

Fuel Filtration System Application Matrix
Use the matrix below to determine the filtrations system that best matches up with our fuel flow requirements and the key
features for design and mounting on your engine. There are multiple filter choices (with and without water separation)
within the families. The flow range values are for fuel filter water separator filtration systems. The flow range would be
higher if applying a non-water separating filter. Families identified as "modular" should be considered if you're interested
in priming pumps and other add-on components.
