This system is used when dust occurs in a large, open area and one booth cannot capture all the dust. It is also useful to reduce odors, humidify the environment or reduce the ambient temperature.

A fogging installation consists of water sprayers placed on the area where the dust concentration is to be reduced. A pump is responsible for sending the properly filtered water to the sprayers, these produce micro-droplets that, in their descent, adhere the dust particles in suspension.
