What is the primary function of an air dryer in a compressed air system?

• A. To increase air pressure
• B. To remove moisture from compressed air
• C. To lubricate moving parts
• D. To cool the air before usage

Answer: (B)

The primary function of an air dryer in a compressed air system is to remove moisture from compressed air. Moisture can lead to various issues in a compressed air system, such as corrosion of components, reduced efficiency, and contamination of air-driven tools and processes. By using an air dryer, the system ensures that the air remains dry, which is essential for maintaining equipment longevity and achieving optimal performance. While increasing air pressure, lubricating moving parts, and cooling the air may be important in their own rights within different contexts of air systems, they do not address the critical need to eliminate moisture. Moisture control is especially important in applications that require clean and dry air, making the role of an air dryer integral to the overall reliability and effectiveness of a compressed air system.
