Claims

[Scope of utility model registration request]

(1) For the gap leading from the suction side to the discharge side between the inner surface of the impeller casing containing the impeller and the blade edge of the impeller,
A radial blower comprising a barrier that acts as a resistance to the airflow flowing from the discharge side to the suction side through the gap.

(2) The radial blower according to claim 1, wherein the barrier is provided in multiple stages from the discharge side to the suction side with respect to the gap.

(3) The radial blower according to claim 1 or 2 of the utility model registration, wherein the barrier is fixed to the inner surface of the blade casing, close to the free end side of the blade edge.
