DUPONT FILMTEC™  TW30 PRO-4040 Commercial Reverse Osmosis Membrane Element

 Direct Replacement for FilmTec TW30-4040, which is now obsolete. 

DUPONT FILMTEC (Formerly DOW FilmTec) TW30 PRO-4040 Elements are the industry standard for reliable operation and production of the highest quality water in commercial applications. This element features the thickest feed spacer (34 mil) available in the industry today to lessen the impact of fouling. DOW FILMTEC TW30 PRO-4040 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.

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-4040 is the direct replacement for TW30-4040 which has been discontinued by the manufacturer.

A must have for the 4th gen Tacoma. Handle looks OEM, fits perfectly and looks great. Installation is super easy and everything needed for installation is provided. Once installed it feels solid, no play and with the exact same texture (leather like) as the original. Overall I highly recommend this handle for your Tacoma

A must have to 3rd Gen Tacoma (2016-2023) owners

Got this driver side grab handle for my 2019 Tacoma Access Cab TRD Sport trim. I'm not sure why Toyota didn't made this a standard features on these trucks. Getting in and out was somewhat a chore without this handle. I'm glad someone finally made this driver side grab handle. Installation was very easy and it even comes with a small plastic pry tool and all the necessary hardware. All the mounting bosses are already on the A-pillar. It fits and the actual handle is very well made and sturdy. It is solid plastic vs some hollow cheaply made. Appearance wise, the plastic, fit/finish, and even the texture of the trim matches the truck's black interior. Great and and a very well made product and now getting in the truck, you can just grab onto the handle and pull yourself in.
