Original oil and gas trade magazine vintage ad for THE FLUOR CORPORATION, Ltd. of Los Angeles, CA. Gas Cleaners for removal of dust from lines. Will meet or excede their guarantee. Model DV features a Venturi spray chamber which aspirates oil in proportion to gas flow rate. All dust particles are thoroughly wetted and dropped out during passage through the expansion areas and mist extraction elements. The liquid removal portion of the scrubber is similar to the WLL unit with two elements and three dropout areas. This unique 1953 old petroleum gas refining equipment magazine advertisement would display beautifully matted and framed. Nice graphics.
