Abstract
A blower device includes a Coanda effect fluid flow amplifier having a suction opening, an outlet opening to provide an amplified fluid flow, an inner passage along an amplifier central axis passing through the suction opening and the outlet opening. An inlet conduit inputs pressurized fluid into the inner passage for drawing the ambient fluid from the suction opening to the outlet opening by Coanda effect, achieving amplified flow. A diffuser downstream of the amplifier includes diffuser side walls that delimit a diffuser inner side surface extending about a diffuser central axis arranged along the amplifier central axis and terminates with a first flow inlet open end facing the outlet opening, and an opposite second flow outlet open end delivers further amplified fluid flow. At least one side opening is upstream of the second flow outlet open end to allow additional ambient fluid to be sucked into the diffuser.
