How often should air tanks be drained?

Air tanks should be drained at the end of each working day to ensure that any accumulated moisture is removed. Moisture can build up in the air tanks due to the condensation that occurs during the cooling of the compressed air. If this moisture is not drained regularly, it can lead to issues such as air compressor damage, freeze-up in cold weather, and the potential for corrosion inside the air tanks. Draining at the end of the day helps to maintain the proper functioning of the air system and ensures that the vehicle operates safely and effectively. This practice is a key maintenance task for drivers of commercial vehicles and promotes the longevity and reliability of the air brake system.
