The Haws AX13S AXION Advantage stainless steel eye/face wash system is designed to replace outdated, under-performing or in some cases, non-conforming installed emergency eyewashes with the medically superior AXION� MSR performance. This revolutionary inverted flow design is the only product on the market that provides a Medically Superior Response consistent with all EMT, emergency room and doctors� office protocols by sweeping contaminants away from the vulnerable nasal cavity. Traditional eyewashes irrigate from the outside edge of the eye back toward the nose, where contaminants can then be flushed into the nasal cavity through the lacrimal punctum, nature�s ocular cavity drain. System includes the stainless steel AXION MSR eye/face wash head, the necessary connecting hardware, along with a tape measure, eyewash measuring gauge and written guidelines to assure installation complies with the ANSI Z358.1 standard. System is designed to replace the eyewash head of most standard wall and pedestal mounted eyewash stations manufactured by Acorn, Bradley, Encon�, Guardian and Speakman�.
