Model 6426 is a lead removal 10" x 2" (25.4 x 5.1 cm) in-line filter with 1/4" NPTF inlet and outlet. Reduces lead from incoming water to levels below 15 ppb (@ flow rate = 0.5 gpm (1.3 L); pressure = 60 psi (4.2 bar)) for up to 500 gallons (1893 L). Filters particulate lead to 10 microns and absorbs soluble lead. Maximum flow of .5 gpm (1.9 L). Therefore, only 1 bubbler may be operated at a time on dual units. Does not leach lead once absorbed. Performance demonstrated under NSF Standard 53 and 42 by independent, certified testing laboratory.
Haws manufactures drinking fountains and electric water coolers to be lead-free by all known definitions including NSF/ANSI Standard 61, Section 9, California Proposition 65 and the Federal Safe Drinking Water Act.
