A blower wheel having a plurality of fan blades is supported in the enlarged portion of the housing for rotation about an axis. A driver is connected to the blower wheel to cause rotation of the blower wheel. A flow straightener assembly is located in the outlet portion of the housing. The flow straightener assembly has first and second fins spaced apart from one another and oriented substantially orthogonal to the axis of the blower wheel. Third and fourth fins are located outside of a respective one of the first and second fins, the third and fourth fins being oriented substantially parallel to the axis of the blower wheel.
