PROBLEM TO BE SOLVED: To provide an air blower including a sound deadening box preventing dew formation on bodies by cold air heat transfer from an air supply ventilation air course to an air exhaust ventilation air course by integrating the two bodies including the air supply ventilation air course and the air exhaust ventilation air course formed therein while preventing heat transfer. SOLUTION: Centrifugal air blowers 9 are provided within the box-shaped bodies 3, and connection plates 19 are arranged on the outer surfaces of the bodies 3 to face surfaces of body suction ports 1 and body blowout ports 2. One of the two bodies 3 serves as the air supply ventilation air course 20, and the other as the air exhaust ventilation air course 21. The two bodies 3 are arranged in parallel while facing each other leaving a clearance 23, and are interconnected by the two connection plates 19 across a space 24 formed between the two bodies 3. Thus, the air blower including the sound deadening box can prevent dew formation between the two bodies 3 by the cold air heat transfer from the air supply ventilation air course 20 to the air exhaust ventilation air course 21.
