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.

摘要： A double-ended blower includes a blower motor assembly supporting opposed first and second shaft ends. The first and second shaft ends have respective first and second impellers attached thereto and enclosed within first and second volutes, respectively. The first volute is connected to an inlet and the second volute is connected to an outlet. The blower motor assembly is supported in a chassis enclosure and a radially outer inter-stage path is between the first and second volute. The second volute is at least partially substantially concentrically nested with the radially outer inter-stage gas path.
