A method for assembling a ventilation system is provided. The method includes providing a ventilation hood that includes a cover portion and a discharge portion extending from the cover portion. The cover portion includes a first aperture, an opposite second aperture, and a cavity therein, wherein an interior of the discharge portion is in flow communication with the cover portion cavity. The method also includes coupling a rotatable member at least partially within the ventilation hood, such that the rotatable member extends at least partially through at least one of the first and second apertures, and such that rotation of the rotatable member induces a windage-driven flow of fluid between a portion of the rotatable member and at least one of the first and second apertures.
