The Lockdown Compact Automatic Dehumidifier is the ultimate in humidity protection. It removes moisture directly out of the air using an ultra-efficient thermo-electric process. Water drains into a holding tank or directly to your drain with the built-in hose connection. Best of all, the Automatic Digital Control turns the unit on only when the humidity gets high and turns it off when it's back under control.FeaturesAutomatic Humidity Control, Set Desired Humidity LevelIdeal for Vaults and ClosetsEasy To See Digital Control Panel600ml tank capacity with AC power Included Extended Length Drainage HoseDimensions: 9.25" L x 6" W x 4.5" D
