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. For micron ratings or particle sizes smaller than 3 micron.
Hastings Filter Efficiency Ratings Bob Is The Oil Guy
Fuel filter micron rating. I have racor 900ma turbine primary filters. Fuel system pre filter before the pump. 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. This filter needs to protect the pump from damage. 1 to 40 micron. Fuel system final filter after the pump.
The results are intriguing. 25 to 400 micron. A micron or 1 micrometer is a length of measurement used by filter manufacturers to measure the diameter of a particle. New fuel systems operate at higher pressures up to 60000 psi and tighter tolerances than ever before. The on engine filters are standard yanmar. A good filter is.
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. 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. 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. While there are other smaller micron ratings those filters below 5 micron are prone to intense clogging or quick debris buildup. Fluid filters can have a micron rating which expresses the filters ability to remove contaminants based on the size of the particles. The smaller the micron rating the faster the filter fills up.
When looking at the different fuel filters it is important to compare apples with apples when considering filtration performance. 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. Did you know a finer micron filter can collect more contamination from the fuel and reach its dirt holding capacity more quickly. It may need replacing more ofeten than a larger micron filter. 5 micron filters with a 5 micron rating remove a large amount of debris from liquid. 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.
