The Pure-Beam™ ultraviolet light is designed for HVAC air disinfection and surface irradiation. Scientific tests show that UV light exposure can significantly reduce air contamination caused by mold, fungus, and viruses, and can cleanse surfaces of mold and slime. Pure-Beam includes a light, ballast, transformer, and bracket. Overall dimensions are small, which makes installation easy. Pure-Beam can be wired directly to a 24V system; a transformer is included if required, allowing for operation using 120, 208, and 240/220 VAC power.
