What is the compressed air pressure in the pharmaceutical industry?

In the pharmaceutical industry, the pressure of compressed air is a key parameter, which directly affects the normal operation of medical equipment and the treatment effect of patients. Generally speaking, the pressure range of compressed air in the pharmaceutical industry varies according to specific use requirements and application scenarios, but it is usually between 0.4MPa and 0.8MPa (that is, 4bar to 8bar).

Specifically:

• General medical use: The output pressure of the air compressor for medical and health purposes is usually between 0.7MPa and 0.8MPa (that is, 7bar to 8bar) to ensure the requirements of medical gas flow and purity.

• Special Section Needs:

  • Wards, operating rooms: compressed air pressure is generally between 0.4MPa and 0.5MPa (that is, 4bar to 5bar).

  • Oral treatment center: Due to the large instantaneous demand, the pressure of compressed air may be slightly higher, usually between 0.5MPa and 0.8MPa (ie 5bar to 8bar).

• Medical air pressure requirements: The rated pressure of medical air is usually 4bar, but the actual output pressure is allowed between 4bar and 5bar. If the output pressure exceeds 5bar or falls below 3.2bar, an alarm shall be set.

• Instrument air pressure requirements: The rated pressure of the gas terminal is 8bar, and the output pressure is between 7bar and 10bar. An alarm shall also be set if the output pressure exceeds 10bar or falls below 6.4bar.

in addition, in addition to pressure requirements, compressed air in the pharmaceutical industry also needs to meet other quality standards, such:

• Cleanliness: The bacteria, oil fume, moisture and odor in the air will affect the health of patients. Therefore, the compressed air must be strictly filtered to ensure that the cleanliness meets the medical standards. The total number of bacteria and actinomycetes in the air should be less than 100cfu/m & sup3;, and the particle size of solid particles should be less than or equal to 0.1 μm.

• Oil content: The oil content in compressed air is also an important indicator. The Chinese Pharmacopoeia and GMP require the oil content of compressed air to be less than 0.1 mg/m & sup3;, and even some require that the oil content should be less than 0.01 mg/m & sup3;, in order to avoid adverse effects on medical equipment and patients.

• Humidity: The humidity of compressed air also needs to be controlled within a certain range, usually requiring humidity below 50% to avoid adverse effects on drug production or medical equipment.

• Temperature: The temperature of compressed air for medical use should be kept within a suitable range, generally between 5°C and 40°C.

generally speaking, the pressure range of compressed air in the pharmaceutical industry is usually between 0.4MPa and 0.8MPa, but the specific value needs to be determined according to the specific use requirements and application scenarios. At the same time, the quality standards of compressed air must also be strictly observed to ensure the normal operation of medical equipment and the treatment effect of patients.
