Powerful and efficient UV cleaner-recirculator with two UV lamps providing air disinfection in hospitals, research laboratories and clinics. The UV air flow cleaner-recirculator consists of 2 germicidal UV lamps, a fan unit equipped with dust filters and a control unit, confined in a flow through chamber. The inner mirror surface of the recirculator chamber reflects ultraviolet rays thereby increasing the density of UV radiation and enhancing the disinfection effect.
