Why is regular drainage of air tanks important?

Regular drainage of air tanks is crucial to ensure optimal braking function by removing moisture and contaminants. In an air brake system, moisture can condense from the air, especially when the air is compressed. This accumulated moisture can lead to freezing in cold weather, which can block the air lines or damage components of the braking system. Additionally, contaminants such as dirt or rust can also enter the air tanks, compromising the efficiency and reliability of the braking system.

By routinely draining the air tanks, you effectively help maintain the cleanliness and reliability of the air system, ensuring that the brakes operate smoothly and safely. Proper maintenance through this drainage prevents issues that could impair braking performance, which is essential for the safety of the vehicle and its occupants.
