    Patent number: 6382911
    Abstract: A multiple outlet centrifugal blower has an impeller that provides both radial and axial airflows that are independent of each other such that an obstruction in one of the airflow does not substantially affect the flow of the other. The blower typically includes a housing having an inlet port, first and second outlet ducts, and an impeller rotatably positioned and supported within the housing. The first outlet duct is configured to receive airflow in a radial direction with respect to the blades of the impeller, and the second outlet duct is configured to receive airflow in an axial direction with respect to the blades of the impeller.
