A portable dust collector which includes a housing having a dust-proof chamber, a motor and blower enclosed within the chamber, a centrifugal blower driven by the motor and exhausting through a diffuser into the housing, a filter bag enclosing the top of the housing, a collection bag enclosing the bottom of the housing, and a support extending downwardly from the housing to the base for providing clearance below the housing sufficient for the collection bag. By positioning the motor within a dust-proof chamber inside the housing, the dust collector has better balance and portability and requires less floor and storage space than prior art collectors with exterior motors. The collector also includes a diffuser which is attached to the blower outlet and is shaped to direct the effluent from the blower downwardly into the collection bag. The diffuser includes a bell-shaped passage having a flared exit opening, which is greater in area than the mouth of the diffuser attached to the blower, so that the blower effluent is reduced in noise velocity prior to entering the collection bag. The motor is oriented radially and horizontally within the housing and the blower inlet oriented horizontally so that an open space is provided for free air flow between the filter and collection bags through the housing.

A portable dust collector comprising: housing having an outer side wall, a substantially open top, a substantially open bottom, and a dustproof chamber within an interior thereof: a motor enclosed within said chamber; blower means driven by said motor for drawing air into said housing, said blower means being enclosed with said interior and having an inlet extending through said housing and communicating with an exterior thereof, and an outlet discharging within said housing; said chamber and blower means being shaped to form a passageway within said chamber between said open top and bottom; filter bag means attached to and enclosing said top for retaining particulates discharged into said interior by said blower while allowing air to pass therethrough; collection bag means attached to and enclosing said bottom for collecting particulates retained in said interior of said housing, whereby particulate-laden discharged from said outlet circulates in the vicinity of said collection bag means and flows through said passageway to said filter bag means; and support means attached to and extending downwardly from said housing side wall for providing clearance below said housing sufficient for said collection bag.
