Abstract
A blower includes a rotor blade rotatable about a central axis extending in an axial direction, a motor that rotates the rotor blade, and a housing that surrounds the rotor blade and the motor. The housing includes stator blades extending in a forward rotation direction of the rotor blade toward an axially lower side of the blower, a porous wall including multiple holes arranged in both the radial direction and in the circumferential direction, and a cylinder portion extending in the axial direction and radially outward of the porous wall. The hole penetrates the porous wall through upper to lower surfaces thereof. The stator blade is axially below the rotor blade. An axially upper end portion of the porous wall is between an axially lower end portion of the rotor blade and an axially upper end portion of the stator blade.
