Big Fogg misting technology is pure and simple. Its foundation is evaporative cooling. In short, we cool you down without getting you wet. A lot of people have the misconception that misting always equals wetness. Not with Big Fogg misting systems. Our misting fans and misting line systems offer three levels of evaporative cooling: high-pressure misting, mid-pressure misting, and low-pressure misting. To generate mist, Big Fogg misting systems pump filtered water through brass and stainless steel atomization nozzles. As the ultra-fine water droplets hit moving air (generated by the pumps, natural wind, or Big Fogg fan units), a cooling evaporative mist is produced.
