Sierra fuel water Separating filterSwith 10 micron technology

Why is 10 micron filtration so important?

facts about micron rating and efficiency?The filter paper or ‘media’ determines what the fuel has to pass through and where the dirt is trapped.

The pore size in the filter media determines micron rating. The percentage of dirt that a filter removes

determines efficiency. Efficiency rating relates to the percentage of particles at a given size that a filter

can capture i.e. 90% of particles 10 micron and larger in size. The higher the efficiency, the higher the

percentage of dirt retained by the filter. Many filter manufacturers claim 10 micron filtration but do not

guarantee the efficiency. Sierra does.

Why 10 micron filtration @ over 90% efficiency?Once in the fuel injection system, 10 micron contaminants and larger can cause severe damage

because of the close tolerances within fuel pumps and injectors. Clogged injectors and/or worn fuel

pumps causes inadequate fuel delivery that can lead to poor fuel economy and engine performance.

facts on ethanol and 99% Water

separationWater is commonly found in fuel systems and can come

from a variety of sources. Condensation, fuel handling and

humid marine environments will increase the presence of

water. Water contaminated fuel can lead to poor engine

performance and even engine damage. Today’s ethanol

blended fuels can increase the chance of water in the fuel

tank. Fuel provides lubrication to the fuel injection system.

Any water that displaces the fuel’s lubricating qualities can

increase the chances of premature wear and component

damage. That’s why it’s so important to use Sierra’s high

efficiency water separating filter.

facts about fuel floWSierra’s 10 micron filters flow over 90 GPH.*

Constant fuel flow to the injectors must be

guaranteed, regardless of how choppy

the water can get or how tight the turn.

Minimizing resistance to flow ensures that

the engine is never starved of fuel. Poor

fuel flow through a filter deprives engines

of their vital needs, causing them to work

harder, lose power and create rapid engine

wear over shorter periods.
