4″ LP-4040 Filmtec RO Membrane

LP-4040 delivers high quality water at low pressure operation and can replace many “first generation” low pressure membrane elements and purify more water in many older systems, especially on cold water feeds. The Filmtec LP-4040 elements feature a 34 mil feed spacer to lessen the impact of fouling and may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning.
