The differences between cleanroom of class 100,class 1000 and

There are different levels of dust-free workshops, ten levels, hundred levels, thousand levels, million levels of workshop design requirements are also different.
What is the difference between hundreds, thousands and thousands? The main reason is that the allowable particle concentration of each particle size in the air is not the same.

• 1, the dust free workshop 0.5 micron allowable particle concentration is less than 3520(pc/m3), 5 micron allowable particle concentration is less than 293(pc/m3).
• 2. The allowable particle concentration of 0.5 micron in the thousand-level dust-free workshop is less than 35200(pc/m3), and the allowable particle concentration of 5 microns is less than 2930(pc/m3).
• 3. The allowable particle concentration of 0.5 micron in the 10,000 dust-free workshop is less than 352000(pc/m3), and the allowable particle concentration of 5 microns is less than 29300(pc/m3).

Hundred, thousand, thousand clean workshop design requirements:
The production workshop has been tested by the Food and Drug Administration, and the cleanliness has reached the 100,000 level pharmaceutical production standard, and the 100,000 level dust-free purification workshop standard stipulates that the number of air dust particles per cubic meter is not more than 35.2 times 100,000, and the number of air changes is generally 15-20 times per hour, which is more suitable for production occasions with lower air cleanliness level. The process treatment measures adopted in the 100,000 dust-free purification workshop are as follows:

• 1, the air conditioning system must be purified air conditioning system after the initial effect, medium effect and high efficiency three filtration treatment. Ensure that the air sent into the room is clean air, which can dilute the indoor polluted air.
• 2, indoor to ensure a certain pressure, to prevent dust-free indoor air interference by the outside air. General purification engineering clean room requires indoor and outdoor pressure difference of 5-10Pa.
• 3, the building envelope must ensure good air tightness, smooth building surface, no dust, no dust, no leakage. GMP plants generally have 10,000, 100,000 and 300,000 levels, of which 100,000 (filling, internal packaging) and 300,000, 100,000 is much stricter than 300,000.
