Medical grade compressed air and high purity air

Technical Analysis of Medical Grade Compressed Air and High Purity Air Suitability Description of Gelanklin Water Lubricated Single Screw Air Compressor

core requirements for 1. medical grade compressed air

medical compressed air is a key medium used in respiratory therapy, surgical instrument drive, drug production and other scenarios in medical facilities. Its quality is directly related to patient safety and medical effects, and must meet the following core requirements:

1. microbial control:
   • compressed air must not contain pathogenic microorganisms (such as bacteria, fungi), usually require microbial content ≤ 1 CFU/m & sup3;(colony forming units per cubic meter of air), to avoid infection caused by airborne transmission.
2. Particulate matter control:
   • the solid particles (such as dust and metal debris) in the compressed air shall be intercepted by a high-efficiency filtration system to ensure that the diameter of the particles is less than or equal to 0.1 μm to prevent abrasion or pollution of precision medical equipment.
3. Moisture and Oil Control:
   • the compressed air shall be completely free of oil pollution, and the moisture content shall be reduced to the pressure dew point below -40 ℃ through the drying equipment to prevent moisture condensation from causing microbial growth or equipment corrosion.

Core Requirements for 2. High Purity Air

high-purity air is usually used in laboratory analysis, precision instrument calibration, semiconductor manufacturing and other scenarios that require extremely high air purity. Its core requirements include:

1. chemical Pollutant Control:
   • compressed air must not contain volatile organic compounds (VOCs), carbon monoxide, carbon dioxide and other chemical impurities, to ensure that the air composition is close to the pure state of natural air.
2. Particulate matter and microbial control:
   • the diameter of the particles needs to be controlled at ≤ 0.01 μm, and the microbial content needs to be close to zero to meet the needs of high-precision analysis or manufacturing.
3. Stability requirements:
   • the pressure, flow rate and purity of compressed air should be stable for a long time to avoid fluctuations in the experiment or production process.

Adaptability of 3. Granklin Water Lubricated Single Screw Air Compressor to Medical and High Purity Air

the enterprise water lubricated single screw air compressor through innovative design, from the source to eliminate the risk of pollution, can efficiently meet the medical grade compressed air and high purity air demand:

1. zero oil pollution technology:
   • water lubrication is used to replace traditional lubricating oil, and no oil molecules enter the airflow during the compression process, completely avoiding the risk of medical equipment failure or drug cross-contamination caused by oil pollution.
   • The water medium is circulated through a special waterway to achieve lubrication, cooling and sealing of components to ensure that the compressed air is absolutely pure.
2. Efficient solid-liquid separation design:
   • the water lubrication in the compression chamber forms a liquid film, which can absorb and scour tiny particles and reduce the residual solid impurities.
   • Equipped with high-efficiency gas-water separator, the moisture and residual particles generated in the compression process are completely separated to ensure that the output air is dry and clean.
3. Microbial Control Support:
   • the internal material of the equipment is corrosion-resistant, easy-to-clean stainless steel and food-grade materials to avoid microbial breeding.
   • Compressed air temperature control, with post-processing equipment (such as sterile filter, activated carbon adsorber) can further reduce the content of microbial and chemical pollutants, to meet the needs of medical and high purity scene.

4. after-treatment equipment and maintenance suggestions

in order to ensure that the compressed air continuously meets the requirements of medical and high purity air, the following post-treatment equipment and regular maintenance should be combined:

1. multistage filtration system:
   • primary filtration: intercept large particles of impurities and protect subsequent equipment.
   • Precision filtration: remove particles above 0.01μm to ensure air cleanliness.
   • Activated carbon filtration: adsorption of trace odor and volatile organic compounds (VOCs), to meet the needs of high purity air.
2. Drying equipment collaboration:
   • freeze dryer: reduce the air temperature, so that the water condensation discharge, pressure dew point -20 ℃ to -40 ℃.
   • Adsorption dryer: adsorb residual moisture through molecular sieve, further reduce the dew point to below -70 degrees C, to meet the needs of high cleanliness scene.
3. Regular inspection and maintenance:
   • compressed air is tested quarterly for microbiological, particulate analysis and chemical contaminants to ensure continued compliance.
   • Regularly replace the filter element, desiccant and water lubrication system components to avoid the risk of contamination due to performance degradation.

5. application cases and effects

the water-lubricated single screw air compressor has been successfully applied in many medical institutions and high-precision manufacturing enterprises:

1. hospital Operating Room:
   • after the compressed air is treated by multi-stage filtration and adsorption dryer, the microbial limit is ≤ 1 CFU/m & sup3;, and the particulate matter content is <0.01 μm, which meets the requirements of surgical instrument driving and respiratory therapy.
2. Pharmaceutical production workshop:
   • compressed air in direct contact with drugs, zero oil pollution characteristics to avoid cross-contamination, to ensure that the quality of drugs in line with GMP specifications.
3. semiconductor manufacturing enterprise:
   • compressed air is used for precision instrument calibration, high purity characteristics to avoid chemical contamination interference, improve product yield.
