Moisture content of compressed air for pharmaceutical

Moisture content control of compressed air for pharmaceutical use and application description of water-lubricated single screw air compressor

requirements for moisture content of compressed air in 1. pharmaceutical industry

pharmaceutical production requires high purity of compressed air, and moisture content is one of the key indicators. According to industry specifications and practical application requirements:

1. general Scenarios the dew point of compressed air should be controlled below -40 ℃. Under this condition, the moisture content is extremely low, which can avoid the accumulation of condensed water in the pipeline and prevent the growth of microorganisms and corrosion of equipment.
2. High cleanliness scene(such as the production of sterile preparations): the dew point needs to be further reduced to below -70 ℃ to ensure that the moisture content is close to zero and meet the stringent requirements of the pharmaceutical production environment for air dryness.

Technical Principle of 2. Water Lubricated Single Screw Air Compressor

the water-lubricated single-screw air compressor used in this enterprise realizes gas compression through the meshing of single screw and star wheel. Its core characteristics are as follows:

1. water lubrication technology: Pure water is used to replace traditional lubricating oil, and water is introduced into the compression chamber through special waterway design to realize lubrication, cooling and sealing of components. The water medium has no risk of oil pollution, ensuring that the compressed air is absolutely pure.
2. compression process: When the screw rotates, the star wheel and the screw tooth groove form a sealed cavity, and the gas is sucked in, compressed and discharged with the volume of the cavity. Water lubrication can reduce component friction and extend equipment life.

Advantages of 3. Water Lubricated Single Screw Air Compressor in Pharmaceutical Field

1. zero Oil Pollution Risk completely avoid cross-contamination of drugs caused by lubricating oil leakage, and meet the requirements of GMP (Good Manufacturing Practice) for the cleanliness of the production environment.
2. Efficient drying performance during the compression process, the water is discharged in time through the drainage device, and the dew point requirement of -40 ℃ to -70 ℃ can be stably reached with the post-processing equipment, so as to meet the gas demand of various pharmaceutical links.
3. Energy saving and stability: Intelligent frequency conversion control technology can automatically adjust the power according to the gas consumption to reduce energy consumption; water lubrication design reduces maintenance frequency and guarantees long-term stable operation.

4. application cases and effects

the water lubricated single screw air compressor has been successfully applied to many pharmaceutical enterprises:

• sterile preparation workshop: The dew point of compressed air is stable below -70 ℃, and the microbial limit is ≤ 1 CFU/m & sup3; to ensure the sterility of drugs.
• Solid preparation production line: The moisture content is controlled at a very low level through post-processing equipment to prevent moisture absorption and agglomeration of materials and improve product quality.
• User Feedback stable operation of the equipment, compressed air quality standards, significantly reduce the risk of downtime due to oil pollution and maintenance costs.

5. Summary

the enterprise water lubrication single screw air compressor through innovative water lubrication technology, for the pharmaceutical industry to provide zero oil pollution, efficient dry compressed air solutions. Its technical characteristics are highly compatible with the needs of pharmaceutical production, which can help enterprises improve product quality and meet the requirements of industry standards.
