A complete range of DOW™ FILMTEC™ 4040-size elements is available to meet a wide variety of customer needs for commercial applications, from high purity water to low total system costs.

  • DOW FILMTEC LP-4040 delivers high quality water at low pressure operation. LP-4040 can replace many "first generation" low pressure membrane elements and purify more water in many older systems, especially on cold water feeds.
  • Features the thickest feed spacer (34 mil) available in the industry today to lessen the impact of fouling.
  • May be cleaned over a wide pH range (pH 1-13) for the most effective cleaning.

Tape-wrapped elements are built with the same high quality membranes and materials of construction as industrial elements, except for the hard outershell, and can be more economical for commercial systems with one or two elements per housing.
