A belt-driven fan characterized by its concise axial relationship of components. A shroud includes a planar apron and a tubular throat intersecting the apron. Linear support members attached to the apron support an electric motor and blade assembly bearing structure. The motor is mounted upon a bracket attached to the support members for selective assembly thereon between operating and shipping positions and with the bracket in the shipping position the electric motor is primarily located within the shroud throat.
