Haws wall-mounted eye/face wash shall include a stainless steel 11-inches round bowl, an Axion MSR eye/face wash head with inverted directional laminar flow which achieves zero vertical velocity supplied by an integral flow control, and stainless steel ball valve equipped with stainless steel ball and stem. Unit shall also include stainless steel wall bracket, stainless steel dust cover, universal sign, 1/2-inches IPS inlet, and 1-1/4-inches IPS waste. 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. Unit is equipped with an in-line 50 by 50 mesh water strainer and stainless steel dust cover, so when debris is present, the irrigation process stays protected. Space efficient stainless steel design and integral wall bracket allow the 7778B to be mounted in a number of easily accessible locations. 8-inches width by 10-3/4-inches height universal emergency sign make the unit easily detected in an emergency. Test card to record weekly checks helps maintain the unit best working quality. Eye/face wash and valve assembly is pre-built and fully water/pressure tested to ensure no leaks and proper function which ultimately reduces installation time and gives the end contractor an added peace of mind. Unit also ships with pre-assembled 16 gauge type 304 stainless steel wall bracket to assist with the installation process. Certified by CSA to meet the ANSI Z358.1 standard for emergency eyewash and shower equipment.
