Filmtec SW30XHR-440i Element

  • $ 645.00

Dow® Filmtec™ SW30XHR-440i elements are the highest rejection seawater RO element in the DOW Filmtec element product line, enabling strict water quality requirements to be met with single pass seawater systems. In addition, the combination of high active area and thick feed spacer results in higher productivity and lower cleaning frequency, which enable sustainable lower lifecycle cost. These elements offer high performance over the operating lifetime without the use of oxidative post-treatments, like many competitive products. This is one reason Filmtec elements are more durable and may be cleaned more effectively over a wider pH range (1-12) than other RO elements.
