Abstract

A portable blower/aspirator device, comprising: - a housing (2) affording a cavity (2a); - an engine (3) housed in the cavity (2a) of the housing (2), the engine (3) being provided with a drive shaft (7); - a cooling fan (9) keyed to an end (71) of the drive shaft (7) in order to aspirate cooling air from an outside environment and to send the cooling air into the housing (2); - a blower impeller (20), keyed to an end (7") of the drive shaft (7) which is opposite the end (71) and arranged internally of a volute (11); - the volute (11) communicating on a side thereof with the housing (2) of the engine (3), and on an opposite side thereof with the outside environment through a second opening (13); in which the blower impeller (20) comprises a wall (22) which faces the first opening (12), a series of radial blades (21) facing the second opening (13) and a circular zone around a hub (23) which circular zone is provided with vents (24) and which circular zone is located facing the first opening (12).
