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 always 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. Eyewash streams provide zero vertical velocity stream engineering with even laminar flow for enhanced comfort, stability and effectiveness. Features around 11" stainless steel receptor and 1 1/4" galvanized stanchion. Includes a mesh in-line strainer to collect line debris, and ball valve with stainless steel ball and stem for durability. Certified by CSA to meet the ANSI Z358.1-2009 Standard for Emergency Eyewash and Shower Equipment
