Abstract
A fluid purification device including an inverted U-shape frame whose legs support a plurality of lamp assemblies each including an ultraviolet lamp received in a protective sleeve. One of the legs is hollow and receives lead wires connected to the lamps through openings spaced along the leg. The protective sleeves at one of their ends are resiliently mounted to the hollow leg at the openings, and seals are provided to prevent fluid from entering into the hollow leg and the protective sleeve. The other ends of the protective sleeves are closed and held in receptacles in the other frame leg which is formed by two plates fixed to each other. "O" rings provided along the other leg receive the protective sleeves to provide flexible seats. An electrical ballast controlling voltage and amperage at the lamps is incorporated in the frame.
