The fan motor power of the large fog cannon is relatively large, and the mist cannon power cable capacity of the general configuration is relatively sufficient. If the diesel or gasoline generator set is used for power supply, the generator set can be adjusted or replaced. If the AC power supply is used, the fan can be turned on first. The instantaneous current load of the fan is relatively large. You can wait for the fan to stabilize and then turn on the water pump, and then spray normally after the voltage is stabilized.
