FUEL PROCESSOR CONCEPT

“ALL-IN-ONE SYSTEM”

Fuel Filter

Fuel rises up to the filter. The patented EleMax®

design allows only a portion of the filter media to be

used maximizing filter life.

Water Separator

Water and large contaminants fall to the bottom of the

body and can be drained away.

Fuel Heater (Optional)

Fuel flows through the heated chamber and up into

the ”SEEING IS BELIEVING”® clear cover filter area.

SEEING IS BELIEVING®

The patented clear cover allows the user to know

when not to change the filter.

20

ALL-IN-ONE FUEL FILTER

EleMax® Fuel Filter System

The patented EleMax® valve and half-wrap

feature is designed to maximize filter life and

minimize filter changes for reduced maintenance

cost.

Best-In-Class Water Separation

StrataPore™ Media provides maximum

protection from emulsified and free water

contamination.

Controlled Fuel Heating (Optional)

Fuel flows through the thermostatically

controlled heated chamber and up into the

“SEEING IS BELIEVING”® clear cover filter area.

“SEEING IS BELIEVING”®

The patented clear cover allows the user to

know when not to change the filter.

21

ELEMAX® FILTER TECHNOLOGY

Fuel level rises as the filter media becomes contaminated, the fuel filter doesn't’t need

replaced until fuel level is at the Top Of The Filter.

The Elemax filter can be identified by the half wrap and a Vapor Pressure Relief Valve

on top of the filter element. The combination of Elemax filter design and Stratapore™

media extend filter change intervals.

2016 ENGINE / DAVCO COMPATABILITY

• The Diesel Pro / Fuel Pro with StrataPore™ media exceeds all

engine manufacturer requirements

— Cummins ISX, ISL, ISB, ISC

— Detroit Diesel 13, 15, 16

— Mack MP7, MP8, MP10

— Navistar N13, MaxxForce DT

— Paccar MX

— Volvo D11, D13, D16

2017 DTNA / CUMMINS WATER SEPARATION REQUIREMENTS

• DTNA and Cummins have defined more stringent fuel water

separator performance specifications for certain engine

models — Detroit DD13, DD15, DD16

— Detroit MDEG

— Cummins ISB, ISC, ISL

• 2017 Navistar, Paccar and Volvo / Mack and Cummins ISX

proprietary engines do not require any performance changes

from current production

• New 2017 DTNA, Detroit and Cummins engine specific

requirements are driven by fuel injection system performance

that is highly sensitive to fuels with low interfacial tension (IFT)

characteristics.

AFFECT OF INTERFACIAL TENSION ON FUEL WATER SEPARATION

• Fuel water separation (FWS) is highly dependent on a fuels

IFT

— The lower the IFT the more difficult to separate water from the fuel

• IFT can be lowered with the addition of anti-wear additives,

lubricity enhancers, rust inhibitors and biodiesel

• Due to the negative impact of water in the fuel on common rail

fuel injection system hardware, Detroit and Cummins have

mandated that primary fuel filters must meet certain

performance criteria with low IFT fuels

— IFT w/traditional fuels 26-30 mN/m

— IFT w/high additive fuels 11-15 mN/m

NEW FUEL FILTER WATER SEPARATION TEST CRITERIA

• Water Separation Requirement (minimum)

— Fuel w/IFT @ 28 ± 2 mN/m

o 98% w/new filter

o 75% w/filter @ end of life

— Fuel w/low IFT @13 ± 2 mN/m

o 90% w/new filter

o 50% w/filter @ end of life
