FILMTEC™ XLE PRO-4040 Brackish Water Reverse Osmosis Membrane Element


DUPONT FILMTEC™ XLE PRO-4040 Elements offer better system performance and economics for small commercial systems by operating at very low applied pressure. FILMTEC XLE PRO-4040 elements are tape-wrapped. In addition to high quality water and low energy costs, FILMTEC membranes also deliver savings by providing long lasting and reliable performance. For added convenience, the elements are available in a dry state for rapid start-up.

FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

DOW and Dupont merged and DOW FilmTec membranes are now sold as DUPONT FilmTec. FilmTec XLE-4040 membrane element has been discontinued by the manufacturer. XLE PRO-4040 is the direct replacement.

Helps dry, cracked feet
Flavor Name: XL silicone socks 2 pairs
We use these on my husband’s cracked feet in the winter and put on a thick cream under these socks. They are nice because hair, dirt and that kind of stuff doesn’t stick to the outside. I do wish them came in more sizes and colors. They were a little small for my husband, but still worked good enough. My husband isn’t thrilled about wearing pink socks around the house. At least it’s just around the house and not out in public though.

Be aware! Once they are on, do not walk! 😂
Flavor Name: XL silicone socks 2 pairs
I absolutely love these things. But the first time I put them on in the living room. The walk to my bedroom was VERY interesting 😂😂😂 I now know I need to put them on and hang out for a bit, or simply go to bed. They do exactly what I need them to do. Feet feel great afterwards! With the right lotion, only need to use one every couple of weeks.

Transformed my feet
Flavor Name: XL silicone socks 2 pairs
After trying several other brands that actually my size did not have the luxury feeling of these. T although x large they have the BEST feel and function. I put lotion on then slip them on and within a few minutes my dry cracked heals are soft. Really a nice product.
