When purchasing a fog cannon for the first time, many 

customers assume that a larger spray volume is always 

better. This is a misconception. A larger spray volume 

actually reduces the distance between the ground and 

the sprayed area, which increases the frequency of water 

discharge from the fog cannon’s water storage tank. 

Consequently, the round-trip fuel consumption rises, 

diminishing the economic benefits.

Factors Influencing Spray Volume

The ideal spray volume of a fog cannon doesn't have a 

fixed parameter. It should be tailored to the specific 

conditions of the sprayed area and seasonal changes. 

For instance:

→mobile dust suppression equipment

 When the ground is extremely dry or air quality is poor,

increase the spray volume.

 During rainy or sunny periods when some roads are still 

wet and cold,decrease the spray volume.

 If there is excessive soil or material on the ground, employ 

an environmental sanitation sweeper or workers to clean 

the fog cannon machine.

Challenges of Excessive Spray Volume

A large spray volume can cause water accumulation on 

low-lying roads. Some of this water might enter sewer 

pipes along the road, leading to wastage of water resources 

and economic development. Excessive soil on the road 

can create muddy conditions, causing secondary pollution 

and potentially blocking sewer pipes. Once the road dries, 

it may produce large-scale yellow sand and environmental 

pollution, necessitating constant sanitation and road 

sweeping efforts.
