Dow Filmtec LE-4040 Reverse Osmosis Membrane

FILMTEC™ brackish water reverse osmosis membrane elements provide consistent, outstanding system performance in light industrial applications.

FILMTEC LE-4040 delivers highest performance at lowest pressure resulting in less energy usage and lower costs. Features the industry's thickest feed spacer (34 mil) to lessen the impact of fouling. May be cleaned over the widest pH range (pH 1-13) for the most effective cleaning. Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.
