Abstract: A chemical discharging fan system has a ducted fan adapted and configured to generate a flow of air from an inlet of the fan into a duct of the fan and through the outlet of the fan. A spray gun is arranged on the fan in the flow of the air generated by the fan. The spray gun has a fluid inlet adapted and configured to receive a pressurized fluid from a fluid supply source. The spray gun is configured to intermittently discharge the fluid from the fluid source into the flow of air generated by the fan. A control is in communication with the spray gun. The control is configured to generate a pulse width modulated signal to cycle the spray gun, which causes the fluid to vaporize upon being discharged from the spray gun into the flow of air generated by the fan.
