The Axeon low energy HF1 series membrane elements are high quality and operate at moderately low pressure. These HF1 membranes consume lower energy than other comparable membranes and produce very high quality water. These membranes offer reliability, high performance and deliver consistent results. They provide increased production, high rejection rates and low energy consumption by operating at low applied pressures. Feature a protective ABS shell. These membrane elements are 100 percent vacuum integrity tested and may also be ordered as individually wet tested. Low energy. High flow capacities. Improved system performance.
