Filter Test Stand of Bubble Method is an indispensable testing equipment for filter material, filter element and filter manufacturer. The principle is that by adding gas pressure to one side of the sample, the gas overflows from the liquid surface on the other side of the sample, there is a single corresponding relationship between the pressure and the maximum aperture of the sample, the maximum aperture of the sample can be obtained by calculation. Bubble test stand has become the first choice test equipment for users in the filtration industry because of its advantages of simple operation, fast test, accurate data, low price, simple maintenance and long service life.

Filter Test Stand of Bubble Method is used for detecting whether the oil filter element of the automobile is larger than the pore of the new filter medium, so as to judge the manufacturing perfection of the filter element and the filter assembly, and whether it can be accepted for further test and use. Filter Test Stand of Bubble Method can also be used for air tightness test.
