Introduction to the selection of air filtration equipment for different situations

I. Air filter selection under normal circumstances

1. Medium-efficiency air filters should be installed in the positive pressure section of the purification regulation.

2. High-efficiency and sub-high-efficiency air filters should be installed at the end of the purification and conditioning system.

3. Medium and high-efficiency air filters should be selected according to the rated air volume or less.
 

II. The filters should be selected separately under special circumstances

1. One-way flow clean room and non-one-way flow clean room.

2. In high-efficiency air purification systems and medium-efficiency air purification systems.

3. Clean rooms with different usage times.
 

III. Air filters that cannot be recycled

1. Equipment used in production processes that are likely to produce a large number of harmful substances and volatile gases during the process.

2. Used in solid oral liquid preparation of granules, finished products drying, and other processes.

3. Used in the process of crushing, weighing, batching, mixing, material making, tablet pressing, coating, filling, etc. of solid materials.

4. Equipment used in the refining and drying processes of APIs refined with organic solvents.

5. Equipment in the radiopharmaceutical production area.

6. Equipment in the pathogen operation area.
