JEM™ Pro-Fog Fluid, Quick Dissipating is a water-based, fast dissipating fog fluid specially designed for use in JEM fog machines. In a studio or theatre environment, a lighter, faster dispersing fog is often preferred. JEM Pro-Fog Fluid, Quick Dissipating offers a less dense effect compared to the benchmark JEM Pro-Fog Fluid and is therefore less likely to interfere with video and film camera focusing.
