gmp clean compressed air quality standard

GMP (Good Manufacturing Practice) has strict requirements on the quality of clean compressed air to ensure that it will not introduce pollution in the pharmaceutical production process and ensure product quality and safety. Specific criteria can be summarized as follows:

1. Microbial control: compressed air must not contain excessive microorganisms (such as bacteria, fungi), through filtration and disinfection measures to control the number of microorganisms at a very low level, to avoid pollution of the production environment or direct contact with drugs.

2. Particulate matter restriction: The suspended dust, fiber and other particles in the air should be strictly controlled to prevent them from adhering to the surface of the product or equipment and affecting the purity of the drug. Particulate matter is typically removed by a high efficiency filter.

3. Moisture management: The moisture content (dew point temperature) of compressed air shall be controlled to avoid corrosion of equipment or damp deterioration of drugs caused by humid air. Drying equipment, such as freeze dryers, is often used to reduce moisture.

4. Oil residue: even if the oil-free air compressor is used, it is still necessary to detect and control the extremely small amount of oil residue in the air to prevent oil from polluting drugs or production equipment.

5. Regular monitoring: a testing process shall be established to regularly sample and test the microorganisms, particulate matter, moisture, oil and other indicators of compressed air to ensure continuous compliance with standard requirements.

the above standards can be adjusted according to the specific production scenario (such as direct contact with drugs), the core is to ensure that the cleanliness of compressed air to meet the quality requirements of drug production.
