When the cleanliness is unqualified, the scanner can scan efficiently. The wind speed can also be tested by anemometer. If the wind speed is less than 0.35, GMP must be replaced. The air volume of the cleanroom is 60% -80% of the rated air volume. One parameter is the resistance, the resistance test is too much trouble, to the technical mezzanine will be a hole in the air outlet, because each installation will not be equipped with high pressure outlet pressure table, so the test resistance is greater than the initial resistance of 2 times to be replaced, If the design of the filter with 484 * 484 * 220, then there is a design problem, according to the size of your room back to the wind count, perhaps 320 * 320 * 220 is enough.
