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.

Necessary for a small dog.
These are great for a small dog! They can get their mouth around it unlike a round ball. My dog is obsessed with these. They are great for making him love a new guest to the house. All they have to do is squeak and throw the toy and they have a new friend!

Great for little dogs but squeaker breaks too easily
My Maltese is about 4.5 pounds and absolutely loves these! He got very excited to play with it right away. The shape is like a slightly flattened ball which is great bc he can pick it up in his tiny mouth. It’s actually quite cute to see him run with it back to me. When you throw it, the way it bounces and rolls is very unpredictable, which I think adds to the fun. Sometimes my pup drops it while running back and it goes rolling or awkwardly bouncing away from him which causes him to get more excited to chase it and grab it again. It’s been a highly entertaining toy for almost a week straight. The only downside is that the squeaker in it isn’t very durable. After a few days of playing and chewing to squeak it himself, the squeaker barely makes any noise. My pup isn’t an aggressive chewer at all so if your dog is an aggressive chewer, the squeaker really will not last.

G for small dogs
My Havanese absolutely loves these small toys, which we refer to as pucks. They are the perfect size for him. His previous favorite was a small green pig, but ever since we purchased these for his second birthday, he has shown no interest in the pig. They are easy to throw and fit comfortably in his mouth. I plan to purchase more. I would not recommend for strong chewers. My only complaint is I wish they all had happy or crazy faces instead of angry or sad ones.

my dogs really loved this toy. I would highly recommend this, but the squeaker is louder than normal so if noise bothers you, then I would not recommend.
