How to Select a Suitable Compressed Air Treatment System?

The compressed air generated by an air compressor system contains numerous contaminants. The degree of contamination varies depending on the environment in which the compressor is located. These contaminants include dust, moisture/water vapor from the ambient air, fine particles, residue from lubricating oil, and mechanical drive debris.

Compressed air carrying these contaminants through the air pipes can cause corrosion and rust within the pipes and control system components, sometimes even compromising product quality. Therefore, the compressed air used in any pneumatic system must be treated. The required air quality standards are determined by the specific scope of usage and application.

Nowadays, compliance with compressed air standards and maintaining high air quality are paramount. This ensures that quality parameters, such as particle content, moisture (dew point), and oil vapor, meet the strict criteria of ISO quality standards.

A complete compressed air treatment system is generally divided into several key stages:

• Purpose: To separate bulk water, moisture from the compressed air.
• Process: Utilize coarse dust filters and condensate separators/slug traps. This is a crucial first step in ensuring clean and dry compressed air.

• Equipment: Combine coarse dust filtration with a condensate separator ensures that water and solid particles are effectively removed, maintaining your compressed air in the best possible condition.

• Purpose: To remove residual water vapor from the compressed air.
• Process: Use dedicated air drying equipment, with the process tailored to your specific system requirements to guarantee optimal performance.

• Process: Use a refrigerated agent to lower the dew point, which causes water vapor to condense. The condensed water, oil, and other impurities are then automatically separated and expelled via an automatic drain valve.

• Process: Use a desiccant material (adsorbent) to absorb moisture from the humid air. The system typically uses two towers (vessels): one for adsorption (drying) and one for regeneration of the desiccant material.

• Purpose: To remove all remaining impurities, including those of very small size, ensuring absolute cleanliness.
• Process: Provide high-efficiency fine filters to achieve this level of purity.

• Purpose: To eliminate impurities and odors, including food odors and oil smells, from the compressed air.
• Process: Utilize an activated carbon filter for effective adsorption of vaporized oil and odors.

• Purpose: To separate oil and water in the condensate before discharging it into the environment. This is essential for environmental protection and compliance with local regulations.

• Oil Mist Eliminator/ Filter (for lubricated systems): Used in oil-lubricated compressor systems to ensure extremely low oil vapor content in the final compressed air.
• Automatic Drain Valve: Utilized to automatically remove condensed water from the system components (like filters and separators), thereby increasing the efficiency of pneumatic equipment.
