• 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. Centrifugal filters 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 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 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.
