ABSTRACT:
A generator engine set includes a brush partition for separating a space defined between an air blower housing and an enclosure into two areas so that an air flow from one area to the other area is substantially prohibited. The brush partition includes a flexible bristle portion and a rigid spline portion. The spline portion is retained in a receiving member on an outer surface of the air blower housing by a clip. The bristle portion extends toward the enclosure and engages an inner surface of the enclosure. Accordingly, a warmed air flow is prohibited from recirculating back into cooling air inlets.
