PURPOSE: An air blower without duct is provided to reduce vibration, noise and power consumption and to improve efficiency of air supply. CONSTITUTION: An air blower comprises two blade parts(100) formed in longitudinal direction and having a plurality of blades formed in airfoil shape with volume and placed in a radial direction of a cylinder; a body(200) horizontally formed in a shape of a duct with both ends closed, having the blade parts placed on both sides of an inside thereof in parallel and comprising a plurality of inlet ports with wire meshes formed on a lower side thereof, an air supplying outlet(220) placed on a front side thereof and divided into two parts, a partition partitioning insides of the inlet ports and the air supplying port in parallel and guiding direction of air supply and a guiding wall placed on a rear upper corner and bending; an electric motor(300) placed on a central inside of the body and having the blade parts coupled to both sides thereof; a switch box(400) comprising a switch(410) placed on a central upper part of the body to control the electric motor, a power line supplying outside electric power to the switch and a power line lead-in port formed for the power line to lead in; and a plurality of fixing ends(500) made of plane sheets both of whose ends perpendicularly bend downward and are coupled to an upper side of the body.
