About RP-W01

RP-W01 is a split-tank water softener series that shares one appearance across three capacities: 32,000, 48,000 and 64,000 grain. The three models differ only in capacity — resin volume of 28 L, 45 L and 60 L, with dimensions of 278 × 240 × 1265 mm, 292 × 268 × 1569 mm and 317 × 317 × 1518 mm.
