摘要： A blower includes a housing including an inlet and an outlet, a motor to drive a rotatable shaft, first and second impellers provided to the shaft, the first and second impellers each including a plurality of impeller blades, a first stationary component provided to the housing and including stator vanes downstream of the first impeller, and a second stationary component provided to the housing and including stator vanes downstream of the second impeller. A first set of stator vanes of the first stationary component is provided around the motor and are configured and arranged to direct airflow along the motor, to de-swirl the airflow and to decelerate air to increase pressure. A blower including a third impeller and third stationary component positioned above the first impeller is also described.
