DUPONT FILMTEC™  TW30 PRO-2540 Commercial Reverse Osmosis Membrane Element

 Direct Replacement for FilmTec TW30-2540, which is now obsolete. 



DUPONT FILMTEC (Formerly DOW FilmTec) TW30 PRO-2540 Elements are the industry standard for reliable operation and production of the highest quality water in commercial applications. DuPont DOW FILMTEC TW30 PRO-2540 elements are tape-wrapped—built with the same high quality membranes and materials of construction as industrial elements, except for the hard outer shell, and are more economical for commercial systems with one or two elements per housing.



DuPont FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. DOW 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.



DuPont FILMTEC TW30 PRO-2540 is the direct replacement for TW30-2540 which has been discontinued by the manufacturer.

Best option for Sim Racing Ambient Lighting
Item Package Quantity: 2
I picked up these Light Bars from Govee specifically for my sim racing setup to be used for ambient lighting, and they’ve exceeded expectations. The RGBIC technology is the standout feature. Being able to display multiple colors on each bar at the same time makes the lighting effects far more dynamic than standard RGB strips. During races, the lighting reacts smoothly to telemetry data—RPM, flags, rev limiter, and speed shifts all translate into immersive ambient effects that genuinely add to the experience. Setup was straightforward, but the real highlight was the seamless SimHub integration. Configuration was quick, and the light bars responded immediately once connected. No complicated workarounds, no lag—just clean, real-time feedback. If you're already using SimHub for dashboards or bass shakers, these integrate perfectly into that ecosystem. Brightness is more than enough for ambient lighting without being distracting, and the diffusion along the 31-inch bars keeps everything looking clean and professional—no visible LED hotspots. The WiFi connectivity has been stable, and the app gives you plenty of customization options outside of racing as well. For anyone building a sim rig and wanting that extra layer of immersion, these are absolutely worth it.

GREAT way to view TV
On initial set up and use of just few days I love this little light bar I'm 74 and I set this up in less than 10 min. Playing with Govee App took about same time for basic functions. The backlighting is great and now my room is lighted during night when I sleepwalk to bathroom. I'll decide later if I want to use adhesive pads. Currently it just sits on TV stand behind TV. All in all it's great! I would definitely buy again and highly recommend. Colors in photos are actually less bright in my room. The Govee App allows many many color variations. Just set up and create color palate for favorite colors and patterns. Eezee Peezee

Outstanding TV backlight edition
Item Package Quantity: 2, Item Package Quantity: 2
This is an excellent addition to a TV backlight. If you go into the GOVEE app you can sync this device to a TV backlight with a camera. You can add up to five lights. I recommend this for either a TV backlight or general ambience in the room at night. UPDATE 2025: I actually have 4 of these. 3 of them I synced with the TV strip light/camera using the GOVEE app for TV watching. The 4th one I use is on ambience lamp. These are made very durable/easy to set up. These things are not cheaply made I highly recommend

Look nice and were an easy setup.
Item Package Quantity: 2
Simple and do what they are supposed to do. I use them to add a bit of flare to my desktop setup for online meetings, etc. If I had to nitpick, I'd say cabling is always interesting to route to reduce desk clutter, but I am not going to remove a star for what pretty much has to be. They look nice too.
