Fluid filters can have a micron rating which expresses the filters ability to remove contaminants based on the size of the particles. 1 micron 39 millionth of an inch 0000039 254 micron visible with magnification.

Oil filter micron rating chart. 40 microns visible with magnification. 10000 miles 16000 km 7500 miles 12000 km 5000 miles 8000 km ford recommended special operating conditions schedule filter type 67l engine 64l engine 60l engine 73l engine air filter check air restriction gauge at 7500 miles 12000 km. 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 25 will filter out contaminants of 25 microns or larger in size and a filter with a micron rating of 5 will filter out contaminants of 5. This filter removes contaminants from the oil and has an almost 100 multi pass efficiency rating. Filters with a 5 micron rating remove a large amount of debris from liquid.
When selecting a filter to match the flow rate try to choose a filter that has your desired flow at 2 8 psid 13 8 55 2 kpa. Same micron rating may provide vastly different performance results. Both filters will essentially remove their respective percentages of particles 20 microns or larger in diameter including virtually all particles large enough to be visible to. Mobil is a well known brand in the automotive industry. They provide oil filters that feature long life performance. If filter b has an efficiency of 50 it will only remove 50 or half of the same contaminant.
Engine oil pre filter inspection filter. Oil filter and oil check message center. 40 to 1270 micron. For example when comparing two filters that are both rated at 5 micron if filter a has an efficiency of 99 it will remove 99 of contaminant 5 micron and larger from the fluid. Engine oil main filter. Select the particle size and media from the chart on the following page.
Select the maximum flow rating of the system in gallons per minute. 1 micron 001 mm. 25 to 400 micron. Fuel system pre filter before the pump. Select the working pressure of the filter element. 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.
This filter needs to protect the suction side of the pump from damage. Purolator classic oil filters are 975 percent efficient and purolator pureone filters are 999 percent efficient the highest efficiency ratings on the market. Crankshaft journals are often finish polished using 23 micron abrasives. Inspect filter minder every. 40 to 90 microns diameter of a human hair. 8 to 40 micron.
