Definition of Class 100,000 Cleanroom Standards:
-
Air Exchange Rate
-
For a Class 100,000 cleanroom, the air exchange rate should not be less than 15 exchanges per hour, with air purification time not exceeding 40 minutes after each exchange. A higher air exchange rate results in a faster dilution and expulsion of indoor air pollutants, leading to a more effective cleanroom environment.
-
Particle Count per Unit Volume
-
In a Class 100,000 cleanroom, the particle count of particles greater than or equal to 0.5 micrometers should not exceed 3,500,000 per cubic meter, and particles greater than or equal to 5 micrometers should not exceed 20,000 per cubic meter. A lower particle count contributes to a better cleanroom environment.
-
Maximum Allowable Microbial Count
-
For a Class 100,000 cleanroom, the airborne bacteria count should not exceed 500 per cubic meter, and the settle plate count should not exceed 10 per culture dish. A lower microbial count minimizes contamination risk to products.
-
Pressure Differential
-
Pressure differentials in a Class 100,000 cleanroom: Consistent pressure differentials are maintained between cleanroom areas of the same cleanliness level. The pressure differential between adjacent cleanrooms with different cleanliness levels should be ≥5 Pa, and between a Class 100,000 cleanroom and a non-cleanroom area should be ≥10 Pa. A larger pressure differential makes it more difficult for external contaminants to enter the cleanroom.
-
The applications of a Class 100,000 cleanroom are extensive and include:
-
Production in high-tech industries such as semiconductor, electronics, and optics.
-
Manufacturing in industries such as pharmaceuticals, biopharmaceuticals, food, and cosmetics.
-
Production in fields like aerospace, navigation, and defense.
-
The construction and operation of a Class 100,000 cleanroom require specialized technical expertise and equipment to ensure it achieves the intended cleanliness standards.
