<p>PURPOSE:To prevent an excessive amt. of air from flowing through a dehumidifier even when the pressure in an air tank is low in order to eliminate a former trouble such that air flows through the dehumidifier in an amt. equal to or more than dehumidifying capacity when the pressure in the air tan is low. CONSTITUTION:In an air supply device supplying air to a plurality of dehumidifiers 2 from a plurality of air sources 1 to supply dehumidified air, bypass passages branched from inlet passages are provided to the inlets of the respective dehumidifiers and a main valve 5 is provided to each of the inlet passages while a bypass valve 6 is provided to each of the bypass passages and both valves are automatically opened and closed to prevent the flow of air in an amt. equal to or more than dehumidifying capacity at the time of the lowering of the pressure in an air tank and the dewing point deficiencies or the flow of non-humidified air at the time of start/stop.</p> |
