DUPONT FILMTEC™ XLE PRO-2540 Low Energy Brackish Water Reverse Osmosis Membrane Element

FILMTEC XLE PRO-2540 Elements offer better system performance and economics for small commercial systems by operating at very low applied pressure. DUPONT DOW FILMTEC XLE PRO-2540 elements are tape-wrapped, built with the same high quality membranes and materials of construction as industrial elements, except for the hard outershell, and are more economical for commercial systems with one or two elements per housing. It may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning. In addition to high quality water and low energy costs, FILMTEC membranes also deliver savings by providing long lasting and reliable performance.

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-2540 membrane element has been discontinued by the manufacturer. XLE PRO-2540 is the direct replacement.

Only vibrates...
Color: Blue
It only vibrates. My dog enjoys it, but it doesn't spin or do what you would expect it to do. I essentially bought my dog a vibrator...

Great dog toy
Color: Blue
My dog loves this interactive ball. It is made with great material and the quality is good. It is rechargeable and it's great to take to dog park and also out in my back yard. My dog enjoys it so much . The battery life is great and it is chew resistant. It don't make much noise and that's a good thing. Size is just right for my dog.

PUPPY APPROVES
Color: Orange
Fun interactive toy. I felt this was a little pricey but watching my puppy playing with it is priceless. She flings it all over the room. As a puppy she chews on it a lot because of teething but there still isn’t a mark on it. Battery lasts a very long time and requires no replacement batteries just a usb connection. It is a little noisy so sometimes I let her play with it without turning it on. All told, it is one of her favorite toys. She is 4 months and weighs 7 pounds, just to give you an idea if it will work for your dog.
