LUBE FILTRATION Lube Filtration Systems

The following pages present Donaldson’s
catalog product offering for Lube Assemblies.
Offering designed both bypass and full flow
filtration.

Use the matrix below to determine the filtration
system that best matches up with our fuel flow
requirements and the key features for design and
mounting on your engine.

Filter Performance Choices
The filter tables provide you with the separate filters
that fit the same head assembly -- these differ by
length and filter performance. Choices are presented
by level of efficiency.

Common Liquid Filtration Terms
Spin On: Filter encased in a metal housing for easier service
Cartridge: These fit into a filter housing which is spun on into a filter head
Cellulose Media: Media from wood fibers
Synthetic Media: This media is comprised of man made fibers and typically results in a lower
pressure drop than cellulose media.
Housing: The place in which the cartridge filter fits into
Micron (µm): The measurement of minute particles of dirt
Pressure Drop: The pressure difference between the upstream and downstream flow
Pressure Regulating Valve: regulates the pressure depending on the liquid force detected at
the end of the receiving piston
Sump or Oil Pan: crankcase or oil reservoir of an internal-combustion engine
Full Flow Lube Filter: filters the oil passing through the engine before it reaches the bearings
Bypass Lube Filter: removes smaller particulates than would be removed by an engine’s
normal filter, so that the need for additional oil or oil changes can be reduced
Baffle Plate or Thread Plate: mounted in the housing below the bearing will help retain the
grease where it is needed
