What is the purpose of compressed air in pharmaceutical factories?

The main uses of compressed air in pharmaceutical factories and the adaptability of Granklin air compressors

Compressed air is an indispensable public engineering medium in pharmaceutical production, and its application runs through the entire process of raw material processing, production and processing, packaging and quality inspection. Granklin’s water-lubricated single-screw air compressor has oil-free design as its core. The compressed air output is highly clean and stable, which can meet the stringent air quality requirements of the pharmaceutical industry. The following are the main uses of compressed air in pharmaceutical factories:

1. Core applications in the production process

1. Instrument and equipment control
   Compressed air serves as a power source and is used to drive pneumatic valves, instruments, and automated control systems (such as pneumatic switches and flow control valves on sterile production lines) to ensure accurate control of the production process. The stable air pressure output by Granklin air compressor can avoid operating errors due to pressure fluctuations and ensure production continuity.

2. Material transportation and handling

   • Powder/particulate material transportation: Through a compressed air-driven pneumatic conveying system, powder materials such as APIs and excipients are transported to reaction kettles, mixers and other equipment to avoid material contamination or stratification;
   • Liquid sub-packaging and atomization: In the production of liquid preparations such as oral liquids and injections, compressed air can be used to control filling accuracy or drive atomization devices (such as the preparation of inhalation preparations).

2. Packaging and sealing

1. Packaging equipment drive
   Compressed air provides power for bottling lines, aluminum-plastic packaging machines and other equipment, driving sealing, labeling, coding and other operations. The oil-free characteristics of Granklin air compressors prevent oil from contaminating packaging materials and ensure the cleanliness of the outer packaging of drugs.

2. Seal and leak testing

   • In sterile packaging (such as freeze-dried powder injection), compressed air is used to maintain a positive pressure environment in the packaging container and prevent the invasion of external microorganisms;
   • Packaging tightness is tested by compressed air (such as bubble method) to ensure that drugs are not moisture or deteriorated during storage and transportation.

3. Environmental control and cleaning

1. Maintain positive pressure in clean area
   Aseptic workshops in pharmaceutical factories (such as Class A and Class B clean areas) need to maintain positive pressure with compressed air to prevent the entry of external contaminated air. The low moisture content compressed air output by Granklin air compressors reduces pipe condensation and prevents excessive humidity in clean areas.

2. Equipment and piping cleaning
   Compressed air is used to purge residual materials in equipment, clean pipes (such as drying after cleaning of reaction tanks), or drive cleaning tools (such as pneumatic vacuum cleaners). Oil-free compressed air avoids the introduction of oil during the cleaning process and reduces the risk of cross-contamination.

4. Quality inspection and R & D support

1. Experimental equipment power
   Analytical instruments (such as gas chromatographs and liquid chromatographs) in quality inspection laboratories may require compressed air as carrier gas or driving gas. The clean air of Granklin air compressors ensures the accuracy of test results.

2. stability testing
   In drug stability studies, compressed air can be used to simulate the storage environment (such as controlling the airflow circulation in the test chamber) to ensure the reliability of test conditions.
