Ozonizer

An ozonizer comprising:

• a pair of electrodes including a grounding electrode and a high voltage electrode;
• a dielectric substrate disposed between said grounding electrode and said high voltage electrode;
• a perforated metal substrate disposed in a gap space between said grounding electrode and said dielectric substrate and being in electrical contact with said grounding electrode, said perforated metal substrate comprising,
• first spacing means interspaced between said perforated metal substrate and said dielectric substrate for maintaining a constant separation gap therebetween,
• second spacing means disposed between said perforated metal substrate and said grounding electrode to maintain said perforated metal substrate in position between said dielectric substrate and said grounding electrode,
• wherein a uniform separation distance promoting a uniform silent discharge is maintained between said perforated metal substrate and said dielectric substrate by said first and second spacing means.
