The XL-4040 membrane element represents a breakthrough in 4" RO technology by delivering an unprecedented 5,000 GPD product water flow—the highest output currently available for a 4"x40" RO membrane. While 8" elements ( 8040)have traditionally been the industry standard for high-flow applications.

Antiscalants are sensitive to the presence of metals like iron and aluminum, which can either deactivate or taint the antiscalant.
