What types of air compressors are commonly used in pharmaceutical factories

In pharmaceutical factories, according to production needs, process characteristics and air quality requirements, the following types of air compressors are usually selected:

1. Oil-free air compressors are widely used in pharmaceutical factories because of their ability to provide pure, oil-free compressed air because of their high air quality requirements for pharmaceutical production. This compressor does not produce oil contamination during the compression process, thereby avoiding the risk of oil contamination of the drug.

2. Screw air compressor is widely used in pharmaceutical factories because of its high efficiency, stability and low noise. It compresses the gas through the mutual engagement of the yin and yang screws, and has the advantages of stable operation, simple maintenance and long service life.

3. Centrifugal air compressor is a good choice for pharmaceutical factories that need a lot of compressed air. It uses a high-speed rotating impeller to obtain kinetic energy for air, and then converts the kinetic energy into pressure energy through a diffuser to provide high-pressure air. Centrifugal compressors are suitable for large pharmaceutical companies and can meet the needs of high flow and high pressure.

4. Piston air compressor: Although the application of piston compressor in pharmaceutical factory is relatively small, but in some specific occasions is still applicable. It compresses gas through the reciprocating motion of the piston in the cylinder, and has the characteristics of simple structure and convenient operation. However, due to the piston compressor may produce certain vibration and noise during operation, and the maintenance cost is relatively high, so its application in pharmaceutical companies is limited.

in summary, the types of air compressors commonly used in pharmaceutical factories mainly include oil-free air compressors, screw air compressors, centrifugal air compressors and piston air compressors. The specific choice of which type of compressor, according to the pharmaceutical production needs, process characteristics and air quality requirements for comprehensive consideration.
