How often should air tanks be drained?

At the beginning of each working day.

At the end of each working day.

Draining air tanks at the end of each working day is crucial for maintaining the efficiency and safety of an air brake system. Moisture can accumulate in the air tanks due to the compression process, and if this moisture is not removed, it can lead to corrosion and potential failure of vital components in the air brake system. Regularly draining the tanks helps to prevent water accumulation, reducing the risk of freeze-ups in colder weather and ensuring that the air supply remains clean and dry for proper functioning. This practice also aligns with safety regulations and best maintenance practices within the industry, ensuring that the air brake system remains reliable throughout its use. Regular maintenance is essential for the longevity and effectiveness of air brake systems, making daily water drainage a critical task for operators.
