Filter efficiency testing is a critical step in evaluating a filter’s ability to remove impurities and contaminants from oil or air. During the test, the actual operating conditions of the engine or equipment are usually simulated, and the contaminant oil or air containing a certain concentration and particle distribution is passed through the filter, and then the amount of contaminant in the filtered oil or air is measured. UT6005. By comparing the amount of contaminants before and after filtration, the filtration efficiency of the filter can be calculated. This test provides a visual reflection of the filter’s filtration performance, ensuring that it can effectively maintain the cleanliness of the oil or air in the actual application, fonho automotive educe engine wear and failure rates, and extend its service life.
Filter dust-holding capacity testing is the process of evaluating the weight of a filter to hold a specific test dust under specific test conditions. Dust holding capacity refers to the amount of dust accumulated when the resistance reaches the specified value (such as 2 times of the initial resistance) due to dust accumulation under the action of a certain air volume. During the test, the filter is installed in a standard test wind tunnel and the upwind end continuously generates dust, measuring the weight of dust passing through the filter or the amount of dust collected on the filter at regular intervals. When the filter resistance reaches the specified value, the weight of the dust contained is the dust holding capacity. This test helps to understand the dust accumulation capacity and life of the filter in actual use, and provides a basis for formulating a reasonable replacement interval.
