摘要： A vortex blower includes an induction motor (1) and a blower portion (2) driven by the motor. The blower portion comprises an impeller (4) and a casing (8). The impeller is so mounted on a rotary output shaft (3) of the induction motor that the impeller is disposed near the induction motor. The casing is so disposed that the impeller is interposed between the induction motor and the casing. An inlet port (10) and an outlet port (11) are provided on an end of the casing opposite to the induction motor. The blower portion has approximately the same diameter as that of the induction motor.

摘要： A blower muffling apparatus includes a blower chamber (26) for housing a blower (VB) therein, an exhaust chamber (32) positioned adjacent the blower body side of a blower disposed in the blower chamber, communicating in one of upper and lower portions with the blower chamber, and having an exhaust port in the other portion, a muffling passage chamber (30) disposed adjacent the blower chamber in the axial direction of the blower, and having one end communicating with the other portion of the exhaust chamber and the other end communicating with a discharge port of the blower through a flexible exhaust duct, and a duct accommodating chamber (36) for accommodating the flexible exhaust duct therein, each of the chambers being surrounded by a sound-absorbing material. Exhaust gas of the blower is discharged from the flexible exhaust duct through the muffling passage chamber (30) and the exhaust chamber (32) to thereby absorb exhaust noise of the blower.
