PROBLEM TO BE SOLVED: To lead a discharge air flow of a first blower to an inlet of a second blower smoothly and cause a static pressure to become higher while causing a body to be reduced in size, in a blower with a silencing box in which two blowers are arranged in series in the body.SOLUTION: The inside of a box-shaped body 5 is divided into a first blower chamber 11 on a side of a body inlet 1 and a second blower chamber 12 on a side of a body outlet 3 by a partition plate 10. The first blower chamber 11 includes a first blower 13, and the second blower chamber 12 includes a second blower 14. The partition plate 10 is configured with: a division surface 21 having a surface parallel to an outlet surface 4; and a first blower outlet surface 22 substantially perpendicular to the outlet surface 4 and connecting the division surface 21 with an inlet surface 2. A discharge port 16a of a scroll casing 20a is connected to the first blower outlet surface 22. In the second blower 14, a rotation axis thereof is arranged in parallel with a rotation axis of the first blower 13, and a discharge port 16b thereof is connected to the body outlet 3. This configuration causes the body to be reduced in size and a static pressure to become higher. |
