Abstract
A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, and a motor adapted to drive the impeller. The housing and the stationary component cooperate to define a volute that directs air towards the outlet. The housing includes a separating wall constructed and arranged to divide the volute into a high speed airpath region and a low speed airpath region.
