ABSTRACT:
Air is introduced from an intake chamber into a plurality of hollow fiber membranes in a casing. The casing is connected to a vacuum pump via a three-way valve and water vapor in air is evacuated through the membranes. Dehumidified or dried air is discharged from a discharge chamber at the ends of the membranes. The vacuum pump is connected to a detector/selector. If the vacuum pump is out of order, it is detected by the detector/selector and another dehumidifier including a depressurizing device is actuated.
