For the classic knee-height fog that rolls across a stage floor and stays there, this section holds the Chauvet Cumulus HP, which delivers the dry-ice look without handling any dry ice: an ultrasonic agitator turns distilled water and fog fluid into a dense mist that hugs the floor on first dances, theatre reveals and camera work. It heats in around two minutes, carries a 7.5 litre water tank alongside 2 litres of fog fluid, and runs from the onboard display, the included wireless remote or two channels of DMX, shipping in a rugged flight case with hoses, clamps and a floor nozzle. Low fog dissipates as it warms, so plan output around the length of the moment and expect large or draughty spaces to eat the effect quickly. Related machines sit in Low Fog Machines, with consumables in Smoke & Haze Fluid.
