Abstract

A fan is for improving air quality, such as in an indoor environment. The fan includes a motor and a rotatable hub coupled to the motor. At least one fan blade includes a first end portion coupled to the rotatable hub and a second end portion radially distant from the rotatable hub. At least one ion generator is carried by the second end portion of the at least one fan blade, such as by a winglet associated therewith. A stationary tube passes through the rotatable hub including a conduit for transmitting power. A rotary coupling is also provided for transmitting power from the conduit to the at least one ion generator.

         6 . The fan of  claim 5 , further including a stationary tube passing through the hub for providing power to the at least one ion generator via a conduit, the rotary coupling connected to the stationary tube. 
     
     
         7 . The fan of  claim 1 , wherein a conduit for supplying power passes from the hub, along the at least one fan blade, and to the at least one ion generator. 
     
     
         8 . The fan of  claim 1 , wherein the at least one fan blade includes a passage extending from the first end to the second end, the passage including wires for transmitting power to the at least one ion generator through the winglet. 
     
     
         9 . The fan of  claim 1 , further including a plurality of fan blades coupled to the rotatable hub, each having a winglet including an ion generator. 
     
     
         10 . The fan of  claim 1 , wherein the at least one fan blade has a length of greater than about six feet. 
     
     
         11 . A fan for improving air quality, comprising:
 (a) a motor;   (b) a rotatable hub coupled to the motor;   (c) at least one fan blade comprising: i. a first end coupled to the rotatable hub, ii. a second end radially distant from the rotatable hub;   (d) at least one ion generator for generating germicidal energy; and   (e) a stationary tube passing through the rotatable hub including a conduit for transmitting power; and   (f) a rotary coupling for transmitting power from the conduit to the at least one ion generator.   
     
     
         12 . The fan of  claim 11 , further including a winglet at the second end of the fan blade for carrying the at least one germicidal generator. 
     
     
         13 . The fan of  claim 12 , wherein the at least one ion generator is mounted to an inner face of the winglet. 
     
     
         14 . The fan of  claim 12 , wherein the at least one ion generator is mounted to the winglet below a plane of the at least one fan blade. 
     
     
         15 . The fan of  claim 11 , further including a conduit passing through the stationary tube for providing power to the at least one ion generator, the rotary coupling connected to the stationary tube. 
     
     
         16 . The fan of  claim 11 , wherein a conduit for supplying power for the at least one ion generator passes from the hub, along the at least one fan blade, and to the at least one ion generator. 
     
     
         17 . The fan of  claim 11 , wherein the at least one blade includes a passage extending from the first end to the second end, the passage including wires for transmitting power to the at least one ion generator through a portion of the at least one blade.
