FUEL FILTRATION
Filtration
How much do you know about filtration?
• Do filters protect you or your investment?
• Do they make you angry because you had
to change them?
• Long lasting filters that never need to be
changed are good? Right?
3
Did you have coffee this morning?
4
Ever try making without a filter?
Pulp or no pulp?
5
How many filters are in a typical
application?
• Fuel --------- Could be as many as 3
• Oil --------- At least one
• Air --------- One plus pre cleaner
• Crankcase -- All engines are moving to
closed crankcase system.
No road tubes.
6
Over the next one hour, we want to provide you
with:
• Basic Fuel, Oil, Air and Crankcase
Filtration Education
• Understanding of filter design
• Application information
• Market players
• Future requirements

Filtration efficiency is based on
fiber technology in 3 areas;
1. Size of fibers
(diameter)
2. Number of fibers
3. Closeness of fibers

Water Separation Filtration Technology
Water Separation is also
based on fiber technology
1. Size (dia.) of fibers
2. Number of fibers
3. Closeness of fibers
4. A coating on the fibers to
increase the interfacial tension
between water, fuel and the
fiber surface.

The Filtration Challenge !
• Transfer Pumps
• Injection Pumps
• Unit Injectors
• Injector Nozzles
• Filter & capture fuel contaminants
to avoid worn, clogged, corroded,
or failed fuel system components.
• Function efficiently for thousands
of miles or hundreds of hours.
16
Current Technology Higher Pressures
Common Rail (H.P.C.R.)
New level of filtration and fuel
delivery requirements
Fuel Injection Designs are Changing!
Filtration technology is necessary
17
Most OEM Performance Requirements:
• > 95% water removal
• High performance in 5%
Biodiesel (B5)
• Longer life
• Higher flow rates
• Material compatibility with
ULSD and Biodiesel
18
• Primary (Pre-Filter) for Vacuum Applications
• Final (Secondary) for Pressure Applications

OIL FILTRATION
Challenge
• Engines are running hotter and
dirtier! ( Remember Injection
pressures?)
• Shorter Oil Drain Intervals
• Higher Soot & Sludge Levels
• Higher Operating Costs
• Engine Oils Have Changed To work
with Emissions Equipment
Oil Contamination Challenge
• Organic Contaminant – Soot due to
Exhaust gas recirculation, high lube oil
temperatures, Silicon, wear metals
• Inorganic Contaminants – Moisture
and fuel dilution
The Microscopic Wrecking Crew
• There is no single property of lube oil that
challenges the reliability of engines more than
suspended particles.
• Small particles ride in the oil indefinitely
because they can not be captured.
• The destruction can be continuous.
Financial Challenge
• Maintenance Costs – High cost of
maintenance – (parts and labor) and down
time for fleet vehicles
• Disposal Costs – High cost to dispose of
the engine oil and filters
The Real Cost Of Poor Filtration
• Short Oil Drain Intervals.
• The oil cleanliness is maintained in many cases by changing it. Oil does not wear out, it simply gets dirty and looses it’s additive package.
• Accelerated engine wear. The current filtration is not adequate to capture the smaller engine damaging particles.
• Solids such as soot are not controlled even though the additives keeps them suspended, they pass right through the standard lube filter. Soot is an abrasive sub micron material that causes wear and increases viscosity which prevents proper oil film that protects the moving parts from friction.
• Poor lubrication reduces engine life. Friction is caused by asperities contacting one another as the two surfaces are rubbed together.
• Oxidation caused by moisture increases viscosity. The oxidation rate of the oil is doubled for every 20 degree increase in temperature.
Engine Oil Flow Process
Typical Lube Oil Circuit
Pressurized lube oil is filtered through the standard 7-40 micron full flow filter
Wear particles under 20 micron are still
flowing through the lube system
Engine Lube Oil Circuit
Fitted With Bypass Oil Cleaner
• Pressurized lube oil is filtered through the full flow filter.
• A secondary bypass oil cleaner, is added for additional filtration
• Oil is now more than 50% cleaner
Industry Trends
• Longer oil drain intervals
• Changes in oil chemistry to meet emissions
• Increased engine temperatures generating more sludge and soot
• “Green” products to reduce waste stream of used oil and filters
• Engineered cellulose and synthetic media
Successful Oil Bypass Products
• Light duty kits include hose and fittings
• GM 6.6L Duramax, Dodge 5.9L/6.7L Cummins and Ford/Navistar Power Stroke 6.0L & 6.4L through 2010
Top Load Bypass Oil Cleaners
• Absolute ISO (Beta) ratings, 3u, 5u, 10u
• High capacity
• Top load for easy service
• Clean element change
• Multiple sizes
• Larger engine sump capacity

CRANKCASE VENTILATION
FILTRATION SYSTEMS
42
The Problem
Open and unfiltered engine crankcase fumes (oily
aerosols) are vented into the atmosphere causing
environmental pollution and engine component
damage.
43
The Problem
Open and un-filtered (Impactor Style) engine
crankcase breather vents which allow piston blow-
by containing oily aerosols to coat intercoolers,
turbochargers, and electronics.
44
The Problem
Engine Performance Problems Related to
Inefficient Crankcase Filtration • Loss of Power
• Increase Warranty Cost
• Emission Compliance Problems

Racor current offers three types of media
• 04 Media is used in Open Systems to where the customer wants to
improve filtration of a regular draft tube.
• 08 Media is used in systems where approximate 80% efficiency is required
• 10 Media is used in system where greater than 90% efficiency is required
- 04 Low Efficiency - 08 High Efficiency - 10 Ultra Efficiency

Current Success Stories with Racor CCV™
Product Line
Several Parker Racor Distributors
have been successful in securing
various CCV contracts with state
grant money. The money was used
to retrofit several hundred busses in
each of the different districts. This
amounts to hundreds of thousands
of dollars for the Distributors just in
installations. The Distributor will
benefit from CCV replacement
elements for years to come.

The Challenge
1. Dust
2. Water
3. Salt
4. Silica
5. Burning Embers
Goals:
1. Remove dust and debris from incoming air
2. Protect engine from dust contamination
Contamination Will Cause:
• Worn piston rings
• Scored cylinder liners
• Excessively worn or failed turbo chargers
• Fouled charge air coolers
• Sludge buildup
Excessive blow-by
High oil consumption
Loss of power
Excessive Smoke
