Abstract: A portable fluid blower having a housing defining an intake region for incoming fluid, an output region, and a fluid path for controllably communicating fluid entering the intake region to the output region at which fluid is discharged from the housing. An impeller on the housing is rotatable around a first axis and draws fluid into the fluid path through the intake region and accelerates fluid drawn into the fluid path so that the fluid drawn into the fluid path through the intake region is accelerated in the fluid path and discharged in an accelerated state at the output region. A drive rotates the impeller around the first axis. The fluid path has a first curved fluid path portion that extends at least partially around the first axis, and a second transition path portion through which fluid communicates from the input region towards the first curved fluid path portion.
