An indirect warm-air device designed to exhaust high temperature warm air generated at an oil burner inside the body to the outside by lowering the temperature to the proper temperature by an air blower at the rear of the body in the first step and an external exhauster with a suction blower at the front of the body in the second step is provided. The device is applicable to a relatively large-scale drying. The indirect warm-air device is characterized in that it contains: a warm-air device including a body with a flue tube(18) at the peripheral rim, a blocking member for blocking the interior of the body, a combustion chamber with a combustion space in the central region of the blocking member, an oil burner(40) on one side of the body to generate heat and a temperature control unit(A); and an external exhauster(70) removably coupled to the front of the body to suck and exhaust warm air. The temperature control unit comprises: a plurality of assembly holes at the edge of the front and rear flange of the blocking member; an outside air exhaust pipe(52) successively inserted into the assembly hoses to exhaust outside air in a heated state; and an air blower(54) installed in the rear region of the body to exhaust the outside air through the outside air exhaust pipe.
