NEW PRODUCTS to the manufacturer. Removal capacity is 6000 grains of ionic solids. The demineralizer unit, a replaceable polyethylene bottle housed inside a metal cabinet, is charged with 30 pounds of anion and cation exchange resins. One charge produces about 600 gallons of deionized water from 10-grain tap water. Water is drawn from a gooseneck spout by operating a control valve from the front of the unit. The cabinet meas ures 36 inches high, 17 Ά inches wide, and 20 inches deep. 21
