FilmTec™ SW30XHR-440i Elements are the highest rejection seawater RO element in the  FilmTec element portfolio, enabling stringent water quality requirements to be met reliably with single-pass seawater systems in most situations. 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. iLEC™ Interlocking End Caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.
