Device and Method for Distributing Chemicals Into the Air Via a Fan

A method comprising:

• providing a chemical discharging fan system comprising a ducted fan, wherein the fan:
• (i) has a duct with an inlet and an outlet spaced from the inlet along the duct of the fan;
• (ii) is configured to generate a flow of air from the inlet into the duct and through the outlet when the fan is energized;
• and (iii) includes a spray gun arranged on the fan in the flow of the air generated by the fan wherein the spray gun has a fluid inlet adapted and configured to receive a pressurized fluid from a fluid supply source, and the spray gun is in communication with a control and receives pulse width modulated signals from the control enabling the spray gun to intermittently discharge fluid from the fluid source into the flow of air generated by the fan;
• energizing the fan to generate the flow of air through the duct of the fan;
• and
• directing the pressurized fluid from the fluid supply source to the fluid inlet of the spray gun;
• and
• operating the control to cycle the spray gun in a manner that the fluid discharged from the spray gun vaporizes upon being discharged from the nozzle into the flow of air generated by the fan.
