The GoFog Humidification System works by pressure being added to the system which is then dispersed through our advanced atomizing fog nozzles. It is a humidifier for static electricity. This generates billions of tiny fog droplets that can be injected directly into a room or HVAC system. This is all done with a small horsepower pump and requires no compressed air. The tiny fog droplets easily evaporate by using the heat energy from the surrounding air.
