Abstract

A housing for directing air propelled by an impeller through an object such as a motor has several arcuate vanes which direct the air radially inward towards ports associated with each vane. The vanes of the housing are placed non-symmetrically about the housing, and each vane has a corresponding vane located 180.degree. around the housing. Sharp corners are eliminated on the back of each vane where the vane meets a main body, where each vane meets an outer rim and/or where each vane meets a base portion of the housing. The disclosed housing increases efficiency in moving air while decreasing the noise of the airflow.
