Chauvet Cumulus is an event-ready, low-lying fog machine that creates thick clouds that hug the floor. The unit’s fast heat up time allows for quick operation and fog on demand. Our Chauvet Cumulus requires buying a full bottle of Martin Heavy Fog Fluid and a bottle of distilled water. The Cumulus’ full 3.25l tank will last approximately 4 hours and a half at maximum output; though at this output the water does have to be refilled every hour (this will require 7.5l of distilled water). Ideal for major venues and stages in both install and rental markets.
