Home built compressor, missing motor & speed fitting. Otherwise complete. DeVilbiss pump, 13 gallon heavy-duty galvanized steel tank. Includes adjustable electric pressure shutoff, adjustable output air pressure regulator, intercooler, and two water separators. Compressor was designed to put out extremely dry air, suitable for spray painting & running air tools. Air passes from pump through air-cooled intercooler, then into a water separator before going into the tank (air is cold and dry going into the tank). When air is used, it comes out of the tank then through the second water separator, eliminating whatever moisture still remains. Extremely dry air-out. Motor was needed for something else, so not included.
