PTFE air filter

Air filtration membrane for cleaning dust, the microporous filtration diaphragm, is made by PTFE material through the special drawing and sintering processing technology . The membrane has lots of merits such as : smooth surface , low friction coefficient, resistance to strong acid and base, resistance to high temperature, high filtration efficiency, long use life, saving energy and reducing consumption, etc. Filtration efficiency for air can reach 99%-99.9999%. PTFE membrane filtering precision for the air particles can reach 3 µm-0.01 µm. Air filtration membrane for cleaning dust ,with other materials added, can be used to make kinds of filtration material such as producing de-dusting filtering bags and air filter etc. Product features 1: smooth surface, cleaning easily, blowing countercurrent . 2: saving energy and reducing consumption, and reduce the operating cost. 3: resistance to high temperature, strong acid and alkaline ; wide application scope. 4: high filtering efficiency, long use life. Application field cement, steel, metallurgy, chemical industry, pigment, petroleum, medicine, tobacco,food processing and other industries’ fume treatment and retrieve.
