In the hot summer, the fog cannon can be used for cooling outdoor public areas, such as squares, parks, open-air stadiums, etc. When the tiny water mist particles emitted by the fog cannon evaporate in the air, they absorb the heat of the surrounding environment, thereby reducing the air temperature.

For example, in some large outdoor music festivals or sports events, fog cannon can provide a relatively cool and comfortable environment for spectators and participants, relieving the discomfort caused by high temperatures.
