         10 . The AFG outlet concentrator of  claim 9 , wherein the transition area reduces the first cross-sectional area by at least 66% and changes the direction of primary air flow by at about 90 degrees at the distal outlet. 
     
     
         11 . An air flow generator (AFG) outlet concentrator, including:
 an AFG outlet interface having a first cross-sectional area and one of an inner envelope or outer envelope and securely and removably couplable to a hand-held AFG outlet, the AFG outlet having a primary air flow direction and one of a second cross-sectional area less than the first cross-sectional area and an outer envelope smaller than the interface inner envelope and a second cross-sectional area greater than the first cross-sectional area and an inner envelope greater than the interface outer envelope;   a distal outlet, the outlet having substantially rectangular shape with its long side substantially parallel to AFG outlet primary air flow direction; and   a plurality of transition areas between the AFG outlet inlet and the distal outlet, the combination of the plurality of transition areas reducing the first cross-sectional area by at least 40% and changing the direction of primary air flow by at least 30 degrees at the distal outlet.   
     
     
         12 . The AFG outlet concentrator of  claim 11 , wherein the AFG is an electric hair dryer.
