Products / Parker / Filters Separators and Purifiers / Fuel Filter Funnel – Racor RFF Series
RFF Series Filter Funnels are designed to protect engines during fueling by removing free water and particulates present in stored gasoline, diesel, heating oil, and kerosene. Capable of removing contaminants down to 50 micron in size.
Dirt and water are practically unavoidable in
stored fuel. Their presence often leads to the formation of
bacteria, corrosive acids, and rust, which can cause plugged
filters, damaged components, decreased combustion efficiency, and,
in severe cases, system failure.
The Racor Filter Funnel (RFF) Series is a line of heavy-duty,
high-flow funnels that help protect engines by removing free water
and contaminants that are often present in stored gasoline, diesel,
heating oil, and kerosene. They feature a built-in DuPont
Teflon®-coated stainless steel screen mesh filter, which utilizes
surface tension to stop water, while allowing fuel to pass through
the funnel and into the engine.
RFF Series funnels are capable of removing free water and solids
down to 50 micron in size and allow users to visually inspect the
cleanliness of their fuel supply during refueling. They are ideal
for fueling lawnmowers, ATVs, chainsaws, snow machines, power
generators, boats, recreational vehicles, motorhomes, motorcycles or
any other type of engine that requires clean, dry fuel on the go.
How it works:
When properly used, the Racor Filter Funnel will separate free water
from hydrocarbon fuels. As fuel is being filtered, heavier free
water and contaminates (rust and grime) are stopped and collected on
the bottom of the funnel. When you have a substantial amount of
water (approximately 1 cup/250 ml), dispose of it properly and
resume refueling
Notes on Use:
• Finger oils can negatively impact the screen’s ability to repel
water. Never touch the screen with bare hands.
• Under some conditions, water may be present in hydrocarbon fuels
in emulsified form. Water may be emulsified in fuel by vibration or
by emulsifying additives such as alcohol, detergents or biodiesel
blends. Water in emulsified form cannot be removed with the Racor
Filter Funnel. In this case, it is best to install a Racor fuel
filter/water separator (Racor FBO for dispensing) to remove
emulsified water from your fuel delivery system before transferring
to equipment.
• Note that excessive filling with captured water will cause head
pressure that can force water through the Teflon® coated mesh. If
the funnel is more than 1/3 covered with water and flow rate begins
to slow, stop fueling immediately, properly dispose of water and
contaminates from the funnel, then continue fueling.
• 2-cycle oil contains detergents, which will allow water to pass
through the filter screen. In this case, the only safe way to filter
out water is to add the 2- cycle oil to the tank after filtering the
fuel through the funnel. Additives containing alcohol are made to
emulsify and bind water to fuel. The filter cannot remove this bound
water. Add additives after fueling. Do not attempt to remove the
filter from the funnel, as the filter is permanently attached to the
funnel. The Racor Filter Funnel is designed to work with fuels only.
• CAUTION! Do not use the Racor Filter Funnel for anything but
filtering fuels; other liquids may compromise the effectiveness of
the filter.
• Another purpose for using a RFF Series funnel is to facilitate the
inspection of fuel for contamination in the form of solids (down to
50 micron) and free water. Don’t forget to check the fuel filter
sump for water. If water or contamination are found, dispose of them
properly.
• To test the Racor Filter Funnel function, slowly fill with water,
roughly 1/3 the way up the screen. This amount of water should not
pass through the Teflon® coated filter screen. Keep this amount in
mind when using the Racor Filter Funnel, knowing that the head
pressure caused by the weight of more than this may cause water to
pass through the screen. If the screen does not repel water it may
have become coated with sticky fuel contaminants. The screen must be
clean to work properly. If necessary, delicately clean the screen
with a soft brush and liquid detergent; allowing it to air dry
before testing water repellency again.
• Always dispose of water, contaminants or dirty fuel in a proper
manner. Periodically inspect the funnel for physical damage. Store
the funnel properly as some fuel will remain on surfaces after use.
Markets:
• Agriculture
• Construction
• Power Generation
• Oil and Gas
• Marine
• Recreational Vehicles (Motorhomes)
• Small Engines (lawnmowers, ATVs, chainsaws, snow machines, etc.)
Applications:
• Diesel
• Gasoline
• Kerosene
• Heating Oil
Benefits:
• Removes free water that often collects at the bottom of fuel cans,
tanks, or drums. Free water formation occurs when humid air inside a
container or tank cools to the point that water condenses out of the
air.
• Removes hard particles present in air that are introduced during
fueling, such as sand and silica.
• Prevents costly injector damage and increases operational life of
downstream filters.
• Saves time and money by eliminating unplanned maintenance and
unscheduled downtime from system component failure.
Features:
• Available in four sizes and flow rates
• PTFE-coated stainless steel filter mesh
• Electro-conductive plastic material
• Corrosion-resistant
• No parts to replace
