Abstract: Introduces the test results of filtering pressure drop and fractional filtering efficiency on a new kind of ePTFE membrane filter. Under the test wind speed is between 0. 5~2. 5 m/s,the pressure drop of this clean membrane filter is about 27~171 Pa;Under the test wind speed is at 1.2 m/min,its collection efficiency is more than 98% for PM2. 5.

Key words: membrane filter, dust removal by filtration, ePTFE, filtration pressure drop, PM2. 5
