How often should vehicle air tanks be drained?

Draining vehicle air tanks at the end of every shift is a best practice for maintaining the braking system and overall air system health of commercial vehicles. Air tanks collect condensation over time due to the moisture in the air that gets compressed during the operation of the air system. If this moisture is not drained regularly, it can lead to several issues such as the freezing of air lines in colder temperatures, which can impair the braking system's functionality.

By ensuring that air tanks are drained on a daily basis, you help prevent moisture-related problems that can lead to costly repairs and unsafe driving conditions. This proactive measure supports optimal performance and safety of the vehicle, aligning with the best practices recommended for maintaining commercial driving equipment.
