Bulk Fuel & Lube
| Contaminants are the enemies of fuels and lubricants, robbing vehicles and equipment of performance and longevity. |
 |
The sophistication of today’s equipment, such as the increase in
injection pressures on diesel engines, requires higher cleanliness
levels than ever before.
Donaldson bulk filtration systems can save on costly component
replacement and minimize equipment and vehicle downtime.
Dakota Fluid Power reduces your total cost of ownership. Removing contaminants with bulk filtration prior to pumping
fluids into equipment allows on-board filtration systems
to do their job better, while supporting the advanced system
technology required to meet new regulations.

on the inlet reduces the risk of contamination in bulk storage tanks and helps maintain desired cleanliness levels.
Compact and easy to replace, Donaldson filters are an important line of defense in maintaining fluid quality, and can be configured for high flow rates while minimizing pressure drop.
| Water absorbing filters, T.R.A.P.™ breathers and Active Reservoir
Vent™ (ARV) products reduce the risk of moisture and contaminants entering a bulk storage tank so that fluids are kept clean and dry. Used together, they’ll help guard fluids from free water, airborne
contamination and microbial growth for as long as they stay in storage. | Because unstable fluids and the
tank itself can be a source of
contamination, final filtration on the outlet with Donaldson filters ensures that
targeted ISO cleanliness levels are achieved. |
Choosing the Ideal Filters for Your System Doesn’t Need to be Complicated Just remember a few key principles:
Fluid viscosity plays an important role in restricting the flow through filters. It’s crucial to select
the proper filter to maintain adequate flow and avoid excessive pressure drops
(see page 13 for viscosity data). Selecting the right micron rating to achieve targeted ISO cleanliness
without overbuilding the system will help avoid unnecessary cost. Different types of oil have different
properties. Choose a filter with the most compatible media-to-fluid properties.

Achieving the Target Cleanliness of a Fluid ISO 4406 contamination codes consist of three numbers corresponding to the number of
particles of 4 microns and larger, 6 microns and larger, and 14 microns and larger present
in the fluid. This page illustrates what it means to start with a contamination of ISO 22/21/18
and target a cleanliness of ISO 14/13/11.
