When should air tanks be drained?

Air tanks should be drained after every working day to remove accumulated moisture and contaminants. This practice is essential because moisture in the air brake system can lead to various issues, including brake failure and freezing problems during colder weather. By draining the air tanks daily, drivers help maintain the integrity and efficiency of the air brake system, ensuring that the brakes operate safely and effectively when needed.

Regularly draining the tanks prevents corrosion and buildup of sludge, which could compromise the overall performance of the braking system. It also contributes to the longevity of the components involved. While some might consider draining the tanks less frequently, such as weekly or monthly, this can lead to neglecting moisture buildup, which poses risks especially in more humid conditions. Therefore, adopting a daily maintenance routine for draining air tanks is a best practice for safe operation.
