Enhance show lighting with the DF-50 Diffusion Hazer. The DF-50 provides a safe, economical non-glycol haze with no heat. The Df-50 produces haze with superior hang-time (3 hours+) while using less than two ounces of fluid per hour. That translates into a low operating cost of about a penny per minute. The DF-50 Diffusion Hazer does not require a warm-up period and can run for 35 hours on 1/2 gallon (2 liters of fog fluid. The fog fluid is odorless when used properly and leaves no residue. The Diffusion Hazer (DF-50) is a patented machine utilizing a triple-filtered system that breaks down the Diffusion Fluid (food-grade mineral oil blend) to a uniform 1-micron-sized droplet.
