This invention has two components, a side delivery spray wand and a transparent plastic package with two compartments. One compartment serves for storage and display of the spray wand, and for guiding and limiting the wand's use in delivering the spray to the paint roller surface. The other compartment serves for storage and display of a paint roller, and is the protective chamber within which a roller is cleaned and spin-dried. The enclosure possesses a small top opening for insertion of the spray wand, and a bottom opening for rapid exhaust of paint-laden solvent. Its two halves are hinged, book-like. When open multiple units nest conveniently. When closed, the compartments are completed, a segment of a paint roller handle is captured, and the seam seals to force all of the paint laden solvent to vent at the exit port.

A pipe source of UV flux has an inner pipe made of UV transmissive material and coated on its outer surface with a UV emitting phosphor. An outer pipe has a cathode array disposed on or near its inner surface, such as an array of thermionic filament cathodes mounted longitudinally or transverse to the length of the pipe, cold cathode arrays formed on the inner surface of the pipe or cold cathode arrays formed on separate substrates which are then attached to the inner surface of the outer pipe. The ends of this two-pipe assembly are hermetically sealed with flanges or end plates at either end of the pipe and evacuated to a pressure below 1×10−3 Torr. Internal spacing rings may be used to provide additional separation between the inner and out pipes. Current from the cathode arrays is accelerated by an anode voltage to strike the UV phosphors when then emit UV light flux which illuminates the inside of the pipe and the fluid material flowing through the inner pipe.
