gmp compressed air quality requirements

Good Manufacturing Practice (GMP) has strict requirements for the quality of compressed air to ensure the safety and reliability of the pharmaceutical production process. The following are some key points of GMP compressed air quality requirements:

1. basic requirements

1. special air source: Compressed air shall be provided with special air source, and oil-free and water-free shall be ensured. If water cooling is required, purified softened water should be used to avoid impurities.
2. Cleanliness compressed air should be sterilized and filtered to meet the national drug packaging container sealing performance and sterilization requirements. Dust and solid impurities in the air should be effectively removed to ensure cleanliness and avoid cross-contamination.

2. specific indicators

1. dust content: The pharmaceutical industry has very strict requirements on the dust in the compressed air. Generally, the particle size channel is controlled to be 0.5 micron particles, and the number of 5.0 micron particles is 0. Specific standards vary with different pharmaceutical production processes.
2. microbial content the number of microorganisms per cubic meter of air must be controlled within a certain range. The specific standards vary with different drug production processes. Generally, there are no more than a number of microorganisms per cubic meter of air.
3. Oil content: GMP requires that the oil content of compressed air should be ≤ 0.1 mg/m & sup3;, and even less than 0.01 mg/m & sup3; in some special cases;.
4. moisture dew point: The moisture dew point should be less than -40 ℃ dew point, or part of the requirements is less than -20 ℃ dew point, in order to prevent water vapor condensation on the drug quality and production equipment.

3. System Requirements

1. gas supply system: The air compression system shall be directly supplied from the air handling unit in the clean and dust-free workshop, and terminal circulating air is not recommended. If circulating air is used for pharmaceutical process requirements, the system should be cleaned and disinfected regularly, and special online monitoring equipment should be used.
2. Filters and purification equipment air filter should be set to effectively remove dust, solid impurities and other pollutants. At the same time, select the appropriate filter and purification equipment, and regularly carry out inspection, maintenance and replacement to ensure its normal operation and purification effect.
3. PIPING LAYOUT AND MATERIALS: The layout of the compressed air pipeline should be reasonable, and the turning and length should be minimized to prevent pressure attenuation. Pipes shall be made of non-abrasive materials, and valves and joints shall be intact and clean.
4. Monitoring and maintenance the compressed air system shall be inspected and maintained regularly to ensure that it can provide the required gas continuously and stably. At the same time, there should be relevant systems and measures to ensure that the compressed air system and ancillary facilities entering the workshop are in an effective clean state.

4. Operation and Training

1. operator training: Air compressor operators should be specially trained and familiar with equipment operating procedures and compressed air quality requirements.
2. Requirements for equipment and facilities: The design and building facilities of the air compressor room should comply with the specifications, and have sufficient space and ventilation conditions.

In summary, GMP has very strict requirements on the quality of compressed air, involving many aspects and specific indicators. Pharmaceutical companies should formulate detailed compressed air quality control plans according to their actual conditions and GMP standards, and strictly implement relevant operating procedures and systems to ensure the safety and reliability of the drug production process.
