Cleanroom Installed Filter System Leak Test
The test is performed to confirm that the final high efficiency
air filter is properly installed by verifying the absence of bybass
leakage in the installation and that the filters are free of defects
(smalle holes and other damages in the filter medium and frame seal)
and leaks (bypass leaks in the filter frame and gasket seal, leaks
in the filter bank framework). The tests are performed by introducing
an aerosol challenge upstream of the filters and immediately scanning
downstream of the filters and support frame or sampling in a downstream
duct. |
