Materail: Surface: 3TO1-TEX expanded PTFE microporous membrane Substrate: glass fiber fabric Performance: High filtration rate up to 100% dust intercepted Low emission exit dust concentration < 10mg/m3 Chemical inert extremely chemical resistant Temperature resistant highest using temperature +260 Low filtration pressure & high air flow Smooth and hydrophob surface dust easily dropping-off Strong and soft substrate material provide enough strength Durable reduced maintenance costs & increased benefit Excellent cleanability cleaning pressure reduced to 2~4 Kg/cm2 Low operation cost R50% lower than normal filter Low blower cost R40% lower than normal filter High recycle rate of powder up to 99.99%. Application: Industrial dust cleaning (cement, steel, electric, etc.) Smoke purification (trash flaming) Air purification. Filtration principle: Surface filtration with ePTFE membrane Particles are collected on the surface of the membrane. As requirement.
