DuPont FILMTEC™ BW30 PRO-2540 Brackish Water Reverse Osmosis Membrane Element (Direct Replacement for DOW FilmTec BW30-2540)

FILMTEC BW30 PRO-2540 Elements are an industry standard for reliable operation and production of high quality water. They are designed for systems smaller than 1 gpm (0.2 m3/h). DuPont FilmTec(Formerly DOW FILMTEC) BW30 PRO-2540 elements offer a hard shell exterior for extra strength and may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning.

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.

FILMTEC BW30 PRO-2540 is the direct replacement for FilmTec

It’s really pretty decent except for one thing.
Color: Grey, Size: 34" - 4 Panel, Color: Grey, Size: 34" - 4 Panel
I bought two of these for my basement and they do look great. They were easy to assemble and I’m happy with them. The problem is that the stitching on the fabric panels are almost the size of a machine basting stitch (which for non sewers means large temporary stitches). Because the panels are tight by design, the stitches had already started to come undone before I could finish assembling everything. Fortunately I can sew and I reinforced all the panels. I had to take the first ones back off the poles to do them but I did the second set before assembling. It’s really not a bad product for the money. It’s quality fabric and the design itself looks great. The stitching looks fine but it’s just not substantial enough for the purpose it is supposed to serve. I can’t imagine why it be sewn so insufficiently. I was able to resolve my issue because I can sew. I wasn’t planning on sewing nor did I really have the time. I could have made it myself but I didn’t want to and that is why I purchased this. I ended up using valuable time. The really unfortunate thing is, I have no other complaints. This is a manufacturing problem.

Inexpensive walls.

We had a hot request for a workstation in the warehouse with some privacy. These have worked great. Easy to assemble. They are lightweight and stable. This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.

Divider
Color: Beige, Size: 4-panel
Looove this so much. No assembly needed just opened the box and it was ready. The quality feels okay, pretty sturdy and does its job. It’s very versatile i use it as a backdrop or a divider. It’s stable and a good value
