Low noise centrifugal blower

Abstract

The present invention provides a centrifugal blower wherein the noise at the cutoff has been substantially reduced by providing a vortex in the air flow near the cutoff to redirect the air flow. A fin projects downwardly into the space created by the exhaust outlet to redirect the air flow away from the cutoff and create a vortex to quiet the air flow.
