When looking at the different fuel filters it is important to compare apples with apples when considering filtration performance. The smaller the micron rating the faster the filter fills up.

Fuel filter micron rating. A good filter is. With the help of sgs herguth labs testing was performed comparing filter medias and micron ratings to see the difference between 3 types of filters baldwin fuel filter 30 micron rating wixnapa fuel filter 15 micron rating catdonaldson fuel filter 2 micron rating. It may need replacing more ofeten than a larger micron filter. New fuel systems operate at higher pressures up to 60000 psi and tighter tolerances than ever before. The results are intriguing. Fluid filters can have a micron rating which expresses the filters ability to remove contaminants based on the size of the particles.
For micron ratings or particle sizes smaller than 3 micron. This filter needs to protect the pump from damage. A micron rating is used to indicate the ability of an oil filter to remove contaminants by the size of the particles that the filter will collect and retain. I have racor 900ma turbine primary filters. For example a filter with a micron rating of 7 will filter out contaminants of 7 microns or larger and a filter with a micron rating of 3 will filter out contaminates of 3 microns or larger. A micron or 1 micrometer is a length of measurement used by filter manufacturers to measure the diameter of a particle.
Microscopic particles in the fuel as small as 2 3 microns can cause abrasive wear severely damaging the fuel injection system and other high pressure engine components. Did you know a finer micron filter can collect more contamination from the fuel and reach its dirt holding capacity more quickly. 25 to 400 micron. Fuel system final filter after the pump. 1 to 40 micron. Fuel system pre filter before the pump.
The on engine filters are standard yanmar. While there are other smaller micron ratings those filters below 5 micron are prone to intense clogging or quick debris buildup. 5 micron filters with a 5 micron rating remove a large amount of debris from liquid. I currently use 2 micron elements and have a pressure drop of 23 inches of mercury a standard vacuum unit of measure across the racors at wide open throttle. A micron rating for a fuel filter is a generalized way of quantifying the ability of the filters media to remove contaminants of a particular size. For example a filter rated for twenty 20 microns means that the filter will capture and contain all particles in the fluid that are 20 microns and larger in diameter.
