Encon Safety Products offers its gravity fed eyewash station (model #01104050). The self-contained station requires only 14 gallons of flushing fluid to meet the ANSI Z358.1-1998 standard. Its low weight (138 lbs. full) and thin profile make the most of application space. A container of Encon's Hydrosep is included as the water treatment additive to help prevent bacterial growth for over 60 days. Encon Safety Products, Houston, TX.
