Abstract
Apparatus for conveying a stream of air in a fanned out distribution pattern over a work surface without use of diverting vanes comprises a duct having an inlet end coupled to the discharge of a tangential blower and an open outlet end for delivering a predetermined volume of air therethrough. The shape of the duct gently flares outwardly from the inlet to the outlet to provide a wider but flattened configuration in the direction of the air path although the cross-sectional areas of the inlet and outlet ends of the duct are substantially equal, whereby air exiting from the duct covers a broader yet extended range. Incorporating an A.C. static eliminator in the duct adjacent the outlet yields a uniform field of air ionization.
