About high efficiency filter leak detection: For food and drug manufacturers, high efficiency filter leak detection refers to the on-site leak detection after the installation of high efficiency filter and its system, mainly to check the small pinholes and other damages in the filter material, such as frame seal, gasket seal and leaky seams on the filter frame. The purpose of leak detection is to check the sealing of the high efficiency filter and its connection parts with the installation frame, find the defects in the high efficiency filter itself and in the installation in time, and take corresponding remedial measures to ensure the cleanliness of the area. Whether there is leakage. The purpose of dust generation is that the dust concentration upstream of the high efficiency filter is low, so if a particle counter is used to detect the leak without dust generation, it is difficult to detect the leak, and additional dust generation is needed to obviously and easily detect the leak.
