Characteristic Test（Filter Characteristic）
Efficiency, service life, and filtration accuracy (removal rate of each particle size) of gas- and liquid-phase filters are measured.
Air filter evaluation
The service life and efficiency of filters are measured by creating an air element to filter a mixture of dust and air. This evaluation can also be performed using a flat sheet instead of the element.
Oil filter evaluation
The service life and efficiency of filter is measured by creating an oil element to filter a mixture of dust and oil.
Fuel filter evaluation
Filter a mixture of fuel for cars, such as light gas oil and dust to measure the cleanliness of fuel after filtration. This evaluation can also be performed using a flat plate instead of the element.
Using a performance check tester for liquid filter, particle removal property (efficiency) and pressure loss (life) are measured. Efficiency data is created by automatic calculation after counting the particles of each measured size (by the counting method).
Using an air filter performance check tester, the particle removal efficiency and dust holding content(DHC) are measured. Regarding the efficiency, the particles of each measured size are counted and data is created by automatic calculation.
