A 7 micron fuel filter with 987 efficiency rating removes 987 of the particles at or above the 7 micron size. Micron ratings are generated by the iso 16889 laboratory test that was designed as a research and development tool.
Best Duramax Fuel Filter That Can Actually Save You Money
Diesel fuel filter micron rating. The measurement is typically the number of particles retained by a filter compared to the number of particles present in the fuel that will pass through the filter. In accordance with the world wide fuel charter cummins and other engine manufacturers specify a minimum fuel cleanliness level of 181613 with a maximum water content of 200 parts per million. Todays oem engine manufactures recommend using a 2 to 10 micron filter to help protect direct injection applications as well as keep the fuel system cleaner due to ulsd quality fuels. A micron rating indicates the ability of a filter to remove contaminants by the size of the particle. I try to check most of the old post and no luck. Is there anyone out there that knows for sure what the new micron rating on the new fuel filter part 9817645 tb 1298b.
Commonly used fuel filters may have multiple efficiency ratings describing their performance. Diesel engines are equipped with a fuel transfer pump that sucks fuel from the fuel tank and supplies it under pressure to the fuel injection system. I ask the parts manager yesterday when i had this new filter installed and he didnt know the micron rating. This is a great question. For example a filter may be described as being 50 efficient on 2 micron particles 75 efficient on 12 micron particles and 98 on 23 micron particles. Instead manufactures of competitive fi lters are using this micron metric in their marketing to create an artifi cial impression of fi ltration quality.
You cannot guess the efficiency of a liquid filter. Theres good reason for the confusion. 1030 micron primary filter element debate is one that has raged for several years now and i suspect the end is nowhere in sight and it applies to all diesel engines from 10 hp sail auxiliaries to engines like yours. The problem with this lies in the nature of the test. The main issue is that up until 2007 most fuel filters used by operators were a 30 micron rated media. Diesel engines using ultra low sulfur diesel fuel meets api performance category cj 4 15w 40 10w 30 5w 40 minimizes foaming provides excellent soot control and fights sludge varnish rust corrosion and wear air filter 67l engines 64l 60l engines 73l engine contains twice the amount of filter media versus conventional pleated filters.
