In the present invention, one end of the casing is partitioned to form an intake air duct and an exhaust air duct adjacent to each other, a silencer is provided in each of the ducts, and an engine-driven fan is installed facing the air inlet of the intake air duct. Since a cross-flow air flow path is formed from the intake port to the exhaust port, it is possible to prevent the vibration noise peculiar to engine-driven devices, and also to prevent the inherent intake and exhaust noise, despite the simple structure. In addition, heat from the compressor and engine does not accumulate inside the casing, which prevents performance deterioration, malfunction, and failure of internal equipment and control parts.
