Most engine wear occurs with particals less than 20 microns. Thank you for choosing FleetFilter.NAPA Gold filters are constructed very good. I hope this article answers questions – a more knowledgeable customer can make better choices. Of the four brands FleetFilter sells (NapaGold by Wix, Fram, Luberfiner, Baldwin), only Wix publishes a nominal micron rating and a beta ratio of their filters. Most filter manufacturers will try to offer the ratings on their filters, but many do not. For example, if one out of every two particles in the fluid pass through the filter, the beta ratio is 2, if one out of every 200 of the particles pass through the filter the beta ratio is 200.Therefore, filters with a higher beta ratio retain more particles and have higher efficiency.įor a NapaGold by Wix 1748, the beta ratio is 2/20 = 10/22, which means that the filter will capture 50% of the 10 micron particles and 95% of the 22 micron particles.( )īeta Ratios and their Efficiencies: Beta Ratio From these measurements a Beta ratio (b) is formulated by dividing the number of particles of a particular size in the upstream flow by the number of particles of the same size in the downstream flow, and is an indicator of how well a filter stops a particulate. Measured samples of the fluid are then taken at timed intervals from both the downstream and the upstream of the filter simultaneously, particles are measured and counted by electronic means using automatic particles counters. Multipass Beta Ratio Testing is the most accurate method of rating filters.You could end up with a 96.7% retention of that micron number. Absolute Micron Rating means that the filter is tested using a single pass of contaminants through a filter media and any particles that pass through are measured.For example, a nominal micron rating of 10 microns at 95% means that the filter media retains 95% of the particles that are 10 microns and larger. Nominal Micron Rating means that the filter can capture a given percentage of particles of the stated size.Measuring a micron rating through testing can be done through three methods: 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. Fluid filters can have a micron rating which expresses the filter’s ability to remove contaminants based on the size of the particles. A MICRON (or 1 micrometer) is a length of measurement used by filter manufacturers to measure the diameter of a particle. ![]()
