Super-Dry Systems ATD Series Compressed Air Dryers are In-Line desiccant air dryers for point-of-use applications. ATD Series In-Line Dryers remove humidity from compressed air lines. Pre-cooled compressed air flows through a desiccant cartridge which adsorbs moisture. Dry compressed air is then delivered at your air tool, nail gun or paint gun. Advantages of In-Line Type Dryers include: low initial capital and installation cost, portable, simple maintenance, low pressure drop, no moving parts, requires no electrical power, can be installed outdoors, can be used in hazardous, dirty or corrosive environments, zero air loss. Ideal for a wide range of air tools, these compressed air dryers protect nail guns against freeze-ups in the winter and liquid in the summer.
