DOW FILMTEC™ LP-4040 Elements deliver high quality water at low pressure operation in commercial applications. It replaces many “first generation” low pressure membrane elements and will purify more water in many older systems, especially on cold water feeds. This element features the thickest feed spacer (34 mil) available in the industry today to lessen the impact of fouling. DOW FILMTEC LP-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.

Used In:

  • Commercial water demineralization


  • High rejection resukts in excellent water quality
  • Durable with good cleanability for long element life
  • Low energy usage reduces power consumption and cost
