The Donaldson Solution

Filtration of bulk oil and diesel fuel

controls the ingression of dirt and water

into equipment when filling up oil or fuel

tanks.

Contamination in lubricating oil or a fuel

can rapidly wear away at expensive

components ultimately causing

catastrophic failure, higher fuel or oil

consumption, greater emissions, leading

to down time and higher operating costs.

Filtration on bulk oil and diesel fuel systems prevents theingression of solid particulate (dirt) into equipment when filling ortopping up oil or fuel tanks. According to one major equipmentmanufacture more than 90% of fuel injection problems are due tounfiltered dirt or water in the fuel.

New emission regulations are driving up diesel injectionpressures, and ever increasing sophistication of plant andmachinery are requiring much improved cleanliness levelscompared to the past.

Customers who are using Donaldson’s fuel filtration

solutions have seen that, in addition to prolonged

component life, there are other unexpected benefits to

clean diesel. These include improved fuel consumption as

well as reduced emissions and service costs.

An essential step to maintaining and cleaning bulk oils

Single and multi-pass filtrationSingle and multi-pass filtration

Filtration is commonly set up for either a single pass

through the filter or multiple passes through the filter.

As you will see below, multi-pass systems are highly

preferred for most applications.

�

�

�

In practice it is expensive and difficult to effectively

clean product in a single pass.

Required cleanliness levels can be achieved using

lower micron efficiency filters.

Smaller systems can be designed to accommodate

high viscosity fluids and/or high flow rates.

Reasons to choose a multi-pass system:

As a general rule, it is necessary to circulate all the oil or

fuel in a storage vessel 6 to 7 times to ensure all product

has been filtered at least once. Take this into account

when designing a new storage system on mobile or

industrial equipment.

Below is a sample of a patch magnified to 100X

showing oil at a cleanliness of approximately ISO

22/20/18, fairly typical of ‘new’ oil.

�

�

Step 1:

Ensure system is sealed and not exposed to elements.

Define target cleanliness levels and filtration objectives.

Step 2:

Chose and size appropriate filtration giving careful

consideration to factors such as fluid viscosity, operating

temperatures and flow rates.

Filter selectionFilter selection

Filter performance is primarily a function of system design. Filter

selection should be done carefully when a system is designed.

However, here is a general guide to consider.

25 micron: provides high dirt holding capacity at a low pressure

drop, for use with high viscosity oils (engine lube and gear oils,

targets ISO cleanliness levels of ISO 18/16/13 or better)

4 micron: Incorporates Donaldson’s new DERT media

(Donaldson Electrostatic ReductionTechnology).

Provides high efficiency useful for diesel fuel and servo valves,

targets ISO cleanliness levels of 14/13/11 or better.

7 micron: provides high dirt holding capacity (useful for general

hydraulic and transmission applications, targets ISO cleanliness

levels of 16/14/11 or better)

� Step 3:

To ensure no further dirt ingress, install a proper breather

system.

This ‘breather’ is a typical example of

‘make-a-plan’ breather. The costs

saved with a DIY approach are small

compared to the costs of resultant

system wear.

Since many contaminants are airborne, any oil or fuel exposed to

the atmosphere will become contaminated unless the air is

filtered or the container is completely sealed.

Use a good quality filter, like the T.R.A.P. (Thermally Reactive

Advanced Protection) breather. The T.R.A.P breather removes

moisture at relative humidity levels as low as 15%. It offers

superior moisture blocking and particulate filtration down to 3

microns at 97%.

During the “exhalation” cycle,

the T.R.A.P. Breather allows

unrestricted airflow outward.

The outflow of dry air picks up the moisture collected by the

T.R.A.P. Breather during intake, and “blows it back out” – fully

regenerating theT.R.A.P. Breather’s water-holding capacity.

TheT.R.A.P. Breather strips

moisture from the incoming air,

allowing only dry air to enter

the circuit.

T.R.A.P. Breather installation on a bulk tank

In addition to particulate filters in diesel systems, water

removal filters can be installed in lines upstream of bulk tanks

as well as downstream on the filling/recirculation lines.These

filters will separate water from diesel with flow rates ranging

from 0-400 L/Min. Each unit is fitted with a manual drain kit in

order to remove the water collected inside the filter housing.
