Description
Dow® Filmtec™ SW30XLE-400i offers an unequalled combination of productivity and rejection. This is the lowest energy seawater element available on the market, enabling lowest operation cost. It is also ideal for two-pass seawater designs and high TDS brackish water applications. Filmtec SW30XLE-400i comes with the unique iLEC™ Interlocking Endcaps that reduce system operating costs and reduce the risk of o-ring leaks that cause poor water quality.
