A dehumidifier for compressed air is provided to discharge dry compressed air by installing a moisture prevention cap at a lower end of an extension unit and installing a step unit on a lower body for preventing moisture from entering to an outlet of an upper body. A dehumidifier for compressed air comprises an upper body(110), a cylindrical member(100), a lower body(120), a water case(140), an extension unit(112), a pipe(136), a snap ring(131a), a moisture prevention cap(115), and a step unit(122). The upper body has an inlet(111), an outlet(113), and a first partition(131). The compressed air is flowed to the inlet and is discharged through the outlet. The first partition is installed at the bottom of the upper body. The cylindrical member is assembled to the upper body. The lower body, assembled to the bottom of the cylindrical member, has a hole where moisture passes through. The water case is assembled to the lower body. The extension unit is coupled with the outlet by a screw unit. The pipe, of which a bore is larger than the extension unit, is perpendicularly fitted to an insert groove formed at the bottom of the first partition. The snap ring fixes the first partition to the extension unit. The moisture prevention cap is fitted to a lower end of the extension unit to be close to an upper surface of the step unit to prevent entering of moisture and has a smaller bore than the step unit. The step unit is protruded upward from an upper surface of the lower body.
