A constructive arrangement introduced into fan having volatilizing function of repellent substance in a strip. The arrangement has a strip containing a substance to be dispersed into the environment is disposed at the front part of the supporting column of the fan, beneath the perimeter of its propellers, creating a pressure difference which provides for the propagation of the dispersion of the substance into the environment, and where the supporting column of the fan, besides acting as a barrier against air flows produced in the environment, preventing the dilution of the volatilized mist, will also enable the enclosure of the electrical wires used in the connections, making energizing the volatilizing combination much easier, more practical and economical.
