JEM Pro-Fog Fluid, High Density is a water-based consumable designed for extended fog effects with high density and slow evaporation. It delivers white, airborne fog with a 30% slower dissipation rate than standard fog fluid under non-ventilated conditions, making it suitable for scenic obscuring, strobe lighting, and 'white-out' applications in military/fire training or performance arts. Formulated with ultra-pure de-ionized water to minimize residue, it operates within 5–40°C ambient temperatures and requires short, infrequent bursts to prevent saturation. Available in 2.5 L, 5 L, 25 L, and 220 L containers, it has a 5-year sealed shelf life and is compatible exclusively with JEM fog effect generators.
