Atmospheric air always contains moisture: the higher temperature, the higher humidity is typical for the air. However, when compressed air is accumulated moisture, the water is condensing on the internal parts of the equipment and pneumatic systems. It is the case of corrosion and reduce the equipment lifetime. Therefore usually the additional air treatment equipment, like air dryer are used to avoid the accumulation of moisture in the pneumatic system.
