Differences between Clean Rooms for Pharmaceuticals And Biotechnology, Electronics Manufacturing, Medical Devices And Food Processing

There are significant differences in the application of Clean Rooms in different fields, mainly in terms of cleanliness levels, control objects, design requirements and application standards. Their main differences are as follows:

1. In addition to temperature, humidity, pressure and other environmental parameters, the control object and cleanliness requirements are reflected in the following areas

Pharmaceutical and biotechnology: The main control of airborne microorganisms and suspended particles to ensure product sterility. Cleanliness levels are usually high, such as A, B, C, D, to meet the strict standards of sterile production.

Electronics Manufacturing: Mainly control airborne particles to prevent contamination of electronic components. Cleanliness level requirements are high, such as level 1 to 8, especially in the chip manufacturing process, the cleanliness of the environment is directly related to the yield of the product. In addition, also need to control static electricity, temperature and humidity and other factors.

Medical equipment: The main control of airborne microorganisms and suspended particles to ensure product sterility. Cleanrooms cleanliness level requirements are usually class A or B to satisfy the standards of aseptic production.

Food Processing: Mainly control airborne microorganisms and suspended particles to ensure food safety. The cleanliness level requirement is usually class 5 to 9, the specific level is determined according to the type of product and production process.

2. Design and construction standards

The standards for pharmaceutical and biotechnology sector require design measures which follow regulations by monitoring microorganism and suspended particulate concentrations.

Building standards for electronic manufacturing must establish strong controls which direct the management of particulates and static power conditions.

Medical devices and food processing facilities need to follow standards which regulate microorganism as well as suspended particulate management.

3. Application areas and cleanliness levels

Cleanroom facilities within pharmaceutical and biotechnology industries follow cleanliness levels starting from A, B, C, D to produce sterile pharmaceutical and biological products.

In electronic manufacturing facilities the cleanliness level typically spans from Grade 1 to Grade 8 which serves the production of semiconductors together with optoelectronics devices and additional high-tech products.

The manufacturing process of medical devices requires cleanliness levels at either Class A or Class B.

The cleanliness standards in food processing adhere to Grade 5 through Grade 9 levels based on product sort and production methodology and influence different food types.
