A bypass motor assembly includes a motor having a rotatable shaft, a working air fan secured to the rotatable shaft and a shroud having an intake eyelet and at least one exhaust apertures. The assembly includes an end bracket having a shaft hole through which the shaft extends. The end bracket and the shroud partially enclose the working air fan, wherein rotation of the working air fan draws air in through the intake eyelet and pushes the air through the plurality of exhaust apertures, the end bracket having a plurality of vanes that form a fan chamber that receives the working air fan such that air expelled by the working air fan is efficiently re-directed by the vanes toward the exhaust aperture. An air intake seal can be disposed between the shroud and the working air fan to further enhance the working air flow.
