Claims

[Scope of utility model registration request]

゛ Casings A and B, which are separated by a partition with a communication section, each contain at least one backward tilting impeller and one forward tilting impeller fixed to the same rotating shaft, and the rotation of both said impellers causes The gas sucked in from the suction port provided in the casing A is sequentially passed from the backward-inclined centrifugal impeller through the communication portion to the forward-inclined centrifugal impeller, and is discharged to the discharge port provided in the casing B. A blower characterized by:
