A fan having a housing including a front piece that is separable but connectable to a back piece is disclosed. The front piece has a first connecting edge and a downstream edge, and the back piece has a second connecting edge and an upstream edge. The second connecting edge is configured to be connected to the first connecting edge. The fan may include a handle, the handle having a first portion integral with the front piece and a second portion integral with the back piece, the first portion configured to be connected to the second portion. The fan may further include air guide ribs provided on an interior surface of the housing and/or a ramp that starts at a location downstream of the upstream edge of the housing and ends at the downstream edge of the housing.

A portable vacuum cleaner is disclosed. The portable vacuum cleaner includes a rechargeable battery and a DC motor. The portable vacuum cleaner further includes a DC power input port for receiving DC power from a remote power source. The DC motor is operable in response to power from either the battery or the remote power source.

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.
