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 hand-time (3 hours plus) 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 2 liters of fog fluid. The fog fluid is odorless and when used properly leaves no residue.
