This paper discusses methods for measuring and evaluating the filtration performance of hydraulic filters and introduces a quasi-single-pass test method. One, well-known method for evaluating filtration characteristics is the multi-pass method. Although the multi-pass test method was specified by the ISO 16889, it allowed changes of upstream contamination level. With the test method, therefore, one can not detect influence of upstream contamination level on filtration performance of fluid power filters. On the contrary, the quasi-single-pass test carried out in this study can reveal influence of upstream contamination level and flow velocity. Experimental results show non-linear characters of filtration performance of fluid power filters.
