ROCK HNF

Hollow NF Filter Core Life Test Hollow NF membrane made of imported medical-grade raw materials from Germany + cross-flow technology is the key of service life. Filter core life test:  150,000 times of dynamic pressure fatigue test result that the membrane element has no rupture, the water quality is good, the seal is good, and there is no water leakage, reaching 1.5 times the relevant test requirements of the National standard, and the filter core life is at least 10 years.

Sense · Simplicity Distinguished Membrane Jinsai · Hollow Fiber NF Membrane 01 Membrane  Material The main material is medical grade polyethersulfone-cellulose (PES-A) imported from Germany 02 Membrane Shape It is mixed evenly at high temperature with the unique precision equipment and special porogen. The high temperature casting liquid is measured and extruded into a hollow NF membrane. 03 Membrane  Filtration Accuracy The membrane wall has pore size of about 1-10nm, high porosity, pressure resistance of up to 0.8 MPa, self-resolving function of pollution, high temperature resistance, acid and alkali resistance and oxidation resistance. 04 Membrane  Filter Core Composed of more than 2,000 hollow fiber NF membrane bundles, the complete filter core is made through filling, sealing and cutting, with a membrane surface area of more than 1.2 square meters.  05 Membrane Characteristics Automatically washing, and pollutants are not accumulate...
