PURPOSE: A device for inspecting the sealing and ventilation performance of a duct and a method for inspecting the performance of the duct using the same are provided to improve indoor ventilation performance by supplying fresh air to an indoor space without a leakage of the air through a ceiling and to minimize unnecessary energy consumption by preventing air ventilated after being leaked out in the inside of the ceiling and ventilated. CONSTITUTION: A device(T) for inspecting the sealing and ventilation performance of a duct is composed of a casing(100), an air supply pipe(200), an air blowing unit(300), an air exhaust pipe(400), an air exhaust blowing unit(500), and air volume measuring units(600). The casing is composed of an air supply duct connecting port(110) and a ventilation duct connection port(120) in one side and an air supply port(110a) and an air exhaust port(120a) in the other side. The air supply pipe is arranged in an inner side of the casing to connect the air supply duct connection port with the air supply port for supplying air. The air supply blowing unit is arranged in an inner side of the air supply pipe to a direction which is close to the air supply duct connection port for supplying air. The air exhaust pipe is arranged in the inner side of the casing to connect the ventilation duct connection port with the air exhaust pipe for exhausting air. The air exhaust blowing unit is arranged in the inside of air exhaust pipe to a direction which is close to the air exhaust duct connection port for exhausting air. The air volume measuring units are respectively arranged in the inner side of the air supply pipe and in the inner side of the air exhaust pipe for measuring the volume of the air flowing into the air supply pipe and flowing into the air exhaust pipe.
