  • Hood and pollution control unit with ultra violet light and electro-static precipitator
    Publication number: 20090042500
    Abstract: A ventilator assembly for removing contaminants in cooking exhaust includes a hood portion having a hood plenum and an exhaust portion downstream of and in fluid communication with the hood plenum. An electro-static precipitator is disposed in the hood plenum or the exhaust portion, and at least one ultra-violet lamp is disposed upstream of the electro-static precipitator for cleaning the electro-static precipitator. The ultra-violet radiation reacts with the cooking exhaust and removes collected contaminants from an electro-static cell of the electro-static precipitator.
