The cooled air from the air cycle machine can no longer hold the quantity of water it could when it was warm. A water separator is used to remove the water from the saturated air before it is sent to the aircraft cabin. Foggy air from the ACM condenses and coalesces the mist into larger water drops in the water separator. The water collects on the sides of the separator and drains down and out of the unit, while the dry air passes through.

A. 从空气循环机出来的冷却空气与其没被冷却时比不再能承载那么多的水。水分离器被用来把水从饱和的空气中除掉，然后空气再进入座舱。来自于空气循环机的水雾装的空气在水分离器中凝结成大水滴。水在水分离器中越来越多然后排出空气循环机，而干燥的空气继续向后流。
