ABSTRACT:
The present invention provides a method and apparatus for varying the high flow and low pressure operating range of a centrifugal blower. Centrifugal blowers are designed and rated for a certain capacity at a certain speed. The present invention provides an apparatus for varying, regulating, or adjusting an inlet capacity of a centrifugal blower. Without the need to redesign or change any blower components, the blower operating range may be changed without affecting blower efficiency. No aerodynamic performance is lost at low flow conditions.
