The Sethco brand activated carbon-filter tubes are designed to be used in any standard single or multi-tube filter chamber. They provide a greater filtration area for greater adsorption plus economy - all in a single double-duty cartridge.
Sethco's activated carbon-filter tube progressively filters out solid particles, then adsorbs organic impurities and finally re-filters the twice-treated liquid. Constructed of inert materials, the multi-layered tube will "purify" the most corrosive acid or alkaline solution including plating solutions to 170 degrees F. An open mesh polypropylene protective outer sleeve gives the tube rigidity and encompasses the polypropylene fluted outer filter of over 120 square inches per 10 inch length of filter area to trap most solids. This is 40% more filtration surface than a conventional flat circular surface.
The fluted design provides greater dirt holding capacity and longer life. Organic impurities are than adsorbed by the next desnse layer of Sethco activated granular carbon. Finally, stray particles down to ten microns are trapped by the double wall inner polypropylene filter providing contaminant free clean and clear solution. The entire construction is layered over a center rigid polypropylene mesh core. Leakproof grooved vinyl end-caps assure a tight "no-liquid-bypass" fit.
