Donaldson P-Series Heavy Duty Filters
 Donaldson Filters
AMSOIL is now
introducing the P-Series of Donaldson filters to complement the Endurance line. The expanded offering of
filtration products features many applications that differ from, and several that coincide with the Endurance
line. Donaldson P-Series filters offer premium filtration at a competitive price. AMSOIL now stocks all of
Donaldson's most popular filter applications.
Donaldson P-Series Lube Filters
Increased engine emissions control and tighter tolerances within the engine require high efficiency filters.
 Donaldson P-Series filters are constructed with full synthetic
or synthetic blend media for high efficiency. The media is embedded deeper into the sealing plastisol than
conventional filters, allowing better sealing longevity. The lube filter can is constructed of heavy gauge
steel, with many models having domed tops that provide superior pressure fatigue performance. The center tube
allows more flow without compromising strength, and the louvered design eliminates tearing during pleat
movement. The can and base plate are I assembled using a fully tucked seam, roll-formed threads, a nitrile
sealing gasket and a compression spring holding all the components in place within the filter.
Donaldson P-Series Air Filters (order)
Donaldson air filter media is made up of
specially formulated fibers designed to trap contaminants such as dust, dirt and soot before they reach the
engine. The media is pleated to maximize the filter surface area and placed between rigid liners to provide
stability and. support. A high quality filter seal is applied or built-in to the open end of the filter to
prevent dirty air from bypassing the filter. Donaldson has developed an extensive range of air filter media to
provide the best engine protection no matter what the operating conditions. For example, using the same particle
size contaminant, for every eight grams of dirt passed through a Luber-finer filter, the Donaldson filter passed
only two grams.
Coolant Filters (order)
Donaldson coolant filters are designed to maintain the proper chemical balance and reduce contaminants in the
engine cooling system. AMSOIL offers a complete line of Donaldson filters with supplemental coolant additive (SCA)
technology for the majority of heavy-duty diesel engines service requirements. SCA's are chemicals in the filter
that are released into the coolant as it passes through. SCA's help resist corrosion and cavitation in the engine
(Note: Although there is no need for SCA's when using AMSOIL Antifreeze & Coolant, the use of Donaldson Heavy
Duty Filters along with AMSOIL Antifreeze & Coolant will not affect performance.). The heavy-duty construction
works in a wide variety of operating environments. Donaldson filters feature heavy-duty thread plates, seals
designed for extreme cold and heat, durable filter media and a unique center tube that increases flow and adds
structural strength.
Fuel Filters (order)
Today's engines are built to more stringent specifications and finer tolerances. Fuel systems, pumps and injectors
require cleaner fuel to achieve better combustion and lower emissions. AMSOIL carries Donaldson's full line of
replacement fuel filters, featuring the latest advances in filter media that makes the difference between engine
power and engine problems.
Hydraulic Filters (order)
Donaldson also develops, manufactures, and markets a full line of hydraulic filters for the protection of machinery
and components in hundreds of applications—in the factory and on heavy duty-mobile equipment. In fact, Donaldson is
considered the world leader in hydraulic filtration.
