• Use high-quality fuels per recommended and
required specifications
• Fill fuel tanks with fuels of “ISO 18/16/13”
cleanliness level or cleaner, in particular for
engines with common rail and unit injection
systems. When you refuel the tank, filter the fuel
through a 4 µm absolute filter (Beta 4 = 75 up to
200) in order to reach the recommended
cleanliness level. This filtration should be located
at the device that dispenses the fuel to the fuel
tank. In addition, filtration at the dispensing point
should remove water to ensure that fuel is
dispensed at 500 ppm water or less.
• Perkins recommends the use of bulk fuel filter /
coalescer units which clean the fuel of both
particulate contamination and water in a single
pass.
• Ensure that you use Perkins Advanced Efficiency
Fuel Filters . Change your fuel filters per
recommended service requirements or as needed.
• Drain your water separators daily .
• Drain your fuel tanks of sediment and water per
the Operation and Maintenance Manual
instructions.
• Install and maintain a properly designed bulk filter /
coalescer filtration system. Continuous bulk
filtration systems may be required to ensure that
dispensed fuel meets the cleanliness target.
Consult your Perkins distributor for availability of
bulk filtration products.
• Centrifugal filters may need to be used as a pre-
filter with fuel that is severely contaminated with
gross amounts of water and/or large particulate
contaminants. Centrifugal filters can effectively
remove large contaminants, but may not be able to
remove the small abrasive particles required to
achieve the recommended “ISO” cleanliness level.
Bulk filter / coalescers are necessary as a final
filter in order to achieve the recommended
cleanliness level.
• Install desiccant type breathers of 4 µm or less
absolute efficiency with the ability to remove water
on bulk storage tanks.
• Follow proper practices of fuel transportation.
Filtration from the storage tank to the application
promotes the delivery of clean fuel. Fuel filtration
can be installed at each transport stage in order to
keep the fuel clean.
• Cover, protect, and ensure cleanliness of all
connection hoses, fittings, and dispensing nozzles.
Consult your local Perkins distributor for additional
information on Perkins designed and produced
filtration products.
