DOW FilmTec Membrane Elements

DOW FILMTEC HSRO-390-FF Heat Sanitizable Full Fit RO Elements

FILMTEC HSRO-390-FF heat sanitizable reverse osmosis membrane elements deliver outstanding quality water with the added capability to withstand sanitization with hot water. HSRO-390-FF elements, manufactured on advanced automated equipment, have the highest active membrane area in the industry. This high area allows system designs with either lower operating flux or cost savings from fewer membrane elements. The full-fit configuration minimizes stagnant areas and is optimal for applications requiring a sanitary design. 

Each HSRO-390-FF is supplied with two end caps (part number 113199) and one coupler (part number 255289). Each coupler includes two 3-912 EPR o-rings (part number 151705).

DOW FILMTEC HSRO-390-FF is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
