Product Description

Ultra Low Pressure, Low Energy, Spot Free - Reverse Osmosis Membrane.

Manufactured using the industry’s leading patented membrane film technology. These Membrane Elements offer reliability, high performance, and deliver consistent results with high rejection rates, which equipment suppliers, distributors, and dealers worldwide have come to rely on. HF5 Membrane Elements are one of the industries highest flowing membranes. They are the only element on the market that operates at a pressure of 80 psi - meaning more energy savings.

These USA made Membrane Elements are the best choice to counter the negative effects of cold water temperatures on reverse osmosis production. •Ultra Low Energy Consumption •High Rejection Rates •Improved System Performance •Superior Quality and Cost Savings •Individually Tested •Made in the U.S.A Membrane Type: Thin Film Composite Maximum Operating Temperature: 110°F (43°C) Minimum Concentrate Flow Rate: 5:1 pH Range, Continuous Operation: 3 - 11 pH Range, Short Term Cleaning (30 Min.): 1 - 12 Maximum Feed Water Turbidity: 1 NTU Maximum Feed Silt Density Index (SDI): 5 SDI Chlorine Tolerance: O PPM Features: High Flow (HF) Ultra Low Pressure Membrane Material Tape Over Wrap Protective ABS Hard Shell Made in the U.S.A.
