ELECTRONIC GENERATOR FOR AIR PURIFICATION An electronic generator for air purification includes a molded plastic housing having a flat floor and a cover. The housing has an air inlet, and a fan pulls air in through the inlet and blows it out through remote outlets. Within the housing and mounted on the floor there is a concave-convex dome made of non-conductive material, and high voltage providing transformer and rectifier structure are mounted within the dome in an inaccessible position. A negative high voltage potential is applied to the conducting concave surface to establish a negative electrostatic charge over the convex surface. The air moving through the housing passes over this convex surface, and negative ions are produced. |
