Question: 1 / 400

What is the purpose of the air dryer in an air brake system?

To cool the compressed air

To remove moisture from the compressed air

The air dryer in an air brake system serves a critical function by removing moisture from the compressed air. Compressed air contains humidity that, if not eliminated, can condense and form water droplets within the air brake system. This moisture can lead to various problems such as corrosion, freezing in cold weather, and contamination of the air brake components, ultimately compromising the system's performance and safety.

By effectively removing moisture, the air dryer helps maintain a dry and clean air supply, ensuring that the braking system operates smoothly and reliably. This function is essential to prevent failure and enhance the longevity of the air brake components, making the air dryer a vital part of the overall air brake system.
