Haws 8904 deck mounted eyeface wash features the medically acclaimed AXION MSR eyeface wash head assembly (patent pending). 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 eye washes 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, natures ocular cavity drain. Unit is activated with simple squeeze lever operation.
