  • Flow range of 1 to 12 GPM provides service for one or two safety eyewashes
  • Shuttle design eliminates valve binding
  • Paraffin-filled thermostats offer industry-leading response times
  • Cold water by-pass capacity of 10 GPM
  • Certified to ANSI Z358.1, ASSE 1071, and NSF/ANSI 372 standards
