Fan Blower Impeller

The fan wheel or impeller is the central factor in the operation of a centrifugal blower since it is the element that moves the air flow, creates pressure, and contains the blower's blades and defines the type of blower.For this type of impeller, flow is produced in a radial direction because the impeller develops static pressure across the longer length of blade. On the front side of the blade a positive pressure is generated pushing the air outwards and on the reverse side of the blade a negative pressure is generated.
