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.
