Container Type Compressed Air Station for Pharmaceutical Clean Air Supply

Compression increases air temperature and concentrates water vapor. As air cools, condensate forms and can cause corrosion, valve malfunction, microbial growth, product defects, and downstream equipment failure. Dryers reduce pressure dew point to a safe level.

Common contaminants include liquid water, water vapor, oil aerosols, oil vapor, dust, rust particles, microorganisms, and acidic condensate. Different filter grades and dryer types are selected according to the required air quality class.

Pressure dew point is the temperature at which water vapor begins to condense at the system pressure. A lower pressure dew point means drier compressed air and better protection for downstream processes.

Oil content depends on compressor type and filtration configuration. Coalescing filters and activated carbon filters can reduce oil aerosols and vapor to meet stricter process requirements, subject to selected filter grade and inlet conditions.

Air compressors and dryers generate heat. Proper ventilation and hot-air ducting remove heat from the container, prevent overheating, protect electrical components, and maintain stable dryer and compressor performance.
