Abstract

Abstract There is provided a generator for forming ozone from air. The generator is adapted to be connected to a power source and comprises a unitary grid assembly which includes a first dielectric plate, a second dielectric plate spaced apart from the first dielectric plate, a wire mesh anode located between the first and the second dielectric plates, a third dielectric plate spaced from the second dielectric plate, a cathode plate located between the second and the third dielectric plates, and a pair of dielectric spacers located between the third dielectric plate and the cathode plate. The second dielectric plate, the pair of spaces and the cathode define a space for the passage of air and the collection of ozone formed from the air. The generator also comprises a blower positioned spaced from but adjacent the grid assembly, for moving the air through the space.
