Abstract
Abstract An electrode air humidifier is provided. The electrodes are suspended in an inner container with water flow contact with the outer container through a pocket chamber, whereby pulsation is greatly reduced or prevented. It is further provided for separation of water drops in the steam and means are provided to reduce the wear of the electrodes by bringing the apparatus to a rapid stop when relatively little water is left in the apparatus.
