The high-efficiency air filters used in clean rooms of different levels are basically the same. If the quality of the FFU filter membrane in the filter clean room is guaranteed, the ventilation parameters (number of air calls or average wind speed) will determine the quality of the clean project. The key factor.
High-efficiency air filters used in clean room projects with stricter requirements currently generally require scanning inspection.
(At present, 100% leak detection of high-efficiency filters at the factory is rare in China).
There are thousands of units in China that can carry out clean room construction, so the number of activation times and average wind speed values for various clean rooms are also different.
