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.
