To provide an alternative configuration of a blower considering necessity.SOLUTION: A blower includes: a housing which has an inlet and an outlet; a motor which drives a rotatable shaft; a first impeller and a second impeller which are provided with respect to the shaft and respectively have plural impeller blades; a first static component which is provided with respect to the housing and includes a stationary blade on the downstream side of the first impeller; and a second static component which is provided with respect to the housing and includes a stationary blade on the downstream side of the second impeller. The first stationary blade set of the first static component is provided around the motor, and configured and arranged so as to feed the air stream along the motor, prevent the revolution of the air stream and increase the pressure by decelerating the air. There is also provided a blower which includes a third impeller and a third static component positioned on the upper side of the first impeller.SELECTED DRAWING: Figure 4 【課題】必要性を考慮したブロワの代替的な構成を提供する。【解決手段】ブロワは、入口および出口を備えるハウジングと、回転可能シャフトを駆動するためのモータと、シャフトに対して設けられた第１の羽根車および第２の羽根車であって、各々が複数の羽根車羽根を含んだ、第１の羽根車および第２の羽根車と、ハウジングに対して設けられ、且つ第１の羽根車の下流側に静翼を含んだ、第１の静的構成要素と、ハウジングに対して設けられ、且つ第２の羽根車の下流側に静翼を含んだ、第２の静的構成要素とを備えている。第１の静的構成要素の第１の静翼セットが、モータの周囲に設けられ、モータに沿って空気流を送るように、空気流の旋回を防止するように、および空気を減速して圧力を上昇させるように、構成および配置されている。また、第３の羽根車と、第１の羽根車の上方に位置決めされた第３の静的構成要素とを備えたブロワが、記載されている。【選択図】図４
