Abstract: A portable air moving device capable of generating an adjustable intensity air flow is provided. The device includes a blower assembly and an intensity adjustment mechanism located within a housing and provides for adjustment of the air flow pattern generated by the device. In one embodiment, the intensity adjustment mechanism includes panels that can be manipulated to adjust the air width of the exhaust air stream. The air width may be increased to decrease the intensity of the air flow and/or the air width may be decreased to increase the intensity of the air flow.
