摘要： An engine-driven blower unit has a casing, an impeller provided inside the casing, and an engine. The casing has a first opening on its wall close to the cooling fan of the engine so that a portion of the air inside the casing is let out through the first opening toward the engine. A second opening is formed so that a portion of the air around the engine is lead to the inside of the casing, to the downstream of the first opening. Thereby, engine-cooling effect is improved, and operational noise is reduced.
