The hazer (haze generator) is very similar in structure to a fog machine and in effect to a fazer. It does not create a dense fog like the fog machine, which should be visible as an effect, but an almost invisible haze to support the multidimensional effect of the light show, i.e. to make the light rays visible. Hazers atomize the fluid using a compressor. This is done via the compressor using ultrasound, not via the evaporation of a heating element as is the case with the fog machine, which is why a special hazer fluid is also required.
